The issue of Sir Robert Plumpton and Alice Foljambe were three sons: 1. William, in his eighteenth year at the time of his father’s death; 2. Godfrey, married to Alice, daughter and coheir of Thomas Wintringham of Knaresborough, by Alice, daughter of John Dobson, before 37 Hen. VI. 1459;y 3. Robert, known only by his father’s deeds of settlement; and two daughters, 1. Joan, contracted, as is abovesaid, to marry William Slingsby, of Scriven, 21 June 1419; 2. Alice, whose alliance is doubtful: but either she or her sister became the wife of John Grene of Newby, com. Ebor. esq. previous to the 1st Jan. 5 Hen. VI. 1426-7.z

Alice is put down as the wife of Richard Marley in a pedigree of Plumpton, in Harl, MSS, 1487. A John Marley was a feoffee for the family 12 Jan. 17 Edw. IV. 1478, and William and Isabel Marley are named in Sir William Plumpton’s Correspondence; but no proof of consanguinity is to be obtained from existing evidences, and the match is too early for a Herald’s Visitation to be relied upon as an authority.

Bryan Plumpton

Father: William Plumpton

Mother: Alice (Gisburn) Plumpton

Notes:
Bryan was remembered in, and was an executor of, and in the will of his cousin, Stephen Scropes dated 24 August 1418.
Testamenta Eboracensia vol 1 pp385-8 (1836)
Ego Stephanus Le Scrop, Archidiaconus Richemund’ in ecclesiâ Ebor., ac utriusque juris inceptor, compos mentis et bonæ memoriæ, xxiiijto die mensis Augusti, anno Domini MCCCCXVIII condo testamentum meum in hunc modum
... Item lego Briano de Plumton2 xl, et j ciphum argenti coopertum, cum armis Yvonis Souche in summo.
... Residuum vero omnium bonorum meorum, non legatorum, pono in dispositione executorum meorum, videlicet Magistrorum Willielmi Alnewyk, Roberti Ragenhill, Roberti Esyngwald, Johannis Armyn armigerorum, Briani Plumpton, Willielmi Normanvyle, et Walteri Flett clerici, et ipsos ordino et constituo executores meos, ut ipsi ordinent et disponant de bonis meis, prout eis melius videbitur expedire. 
   2 Brian de Plumpton was a younger son of Sir William Plumpton, of Plumpton, Knight, by Alice, daughter and heir of John Gisborne, who was Mayor of York in 1371. Sir William Plumpton was beheaded in 1405; and to Brian, his son, a legacy of £10 might perhaps be very acceptable. The Plumptons and Scropes were closely connected by marriage.
A rough translation of these parts of the will is:
I, Stephen Le Scrop, Archdeacon of Richmond in the diocese of York, and initiator of both laws, of sound mind and good memory, on the 24th day of August 1418, make my will in this manner
... Also I bequeath to Brian de Plumton £10, and one cup covered with silver, with the arms of Yvon Souche at the top.
... The remainder of all my goods, not bequeathed, I place at the disposal of my executors, namely, Magistrate William Alnewyk, Robert Ragenhill, Robert Esyngwald, John Armyn, esquires, Brian Plumpton, William Normanvyle, and Walter Flett, clerk, and I order and appoint them my executors, to arrange and dispose of my goods, as it shall seem best to them.

  In the partition of her parents’ property, Alice Plumpton had allotted to her share a messuage in Skeldergate in York, another upon Byshophill, “et toutz les martisounz, apelles en Knyles deles of the Kuyes, que furount Johan de Gysburne en les preetz de Bushopthorp, pres de Everwyk,” and a rent of five marks out of lands and tenements in the town of Ripon, together with all the tenements belonging to her said father in North-street, in the city of York.o Of this property she made a settlement, 26 Oct. 4 Hen V. 1416, whereby she directed Richard Kendale, parson of the church of Ripley, and other co-feoffees, to make an estate of the lands and tenements in Ripon to her son Thomas and the heirs of his body; remainder in like form to her sons Brian and Richard; and the tenements in North-street were similarly settled on her son Richard, in the first instance, with like remainders to Brian and Thomas.
... Brian Plompton, one of the sons above named, had a legacy of xli and a silver dish with cover, having upon it the arms of Ivo le Zouche, under the will of Stephen le Scrope, archdeacon of Richmond, his cousin, dated 24 Aug. 1418, and proved the 7th of September following, being at the same time one of the executors, in which capacity he had a further legacy of ten marks.q Brian was party to a bond dated 31 Dec. 1418,r but he, as well as his brother Thomas, who died 18 July 1420, was deceased without issue, in the lifetime of his mother; for by a fresh settlement, bearing date 12 Sept. 2 Hen. VI. 1423, she gave all her lands and tenements, both in North-street York, and at Ripon, to her son Richard de Plumpton and the heirs of his body

George Plumpton

Father: William Plumpton

Mother: Alice (Gisburn) Plumpton

Occupation: Clergyman
George was a Bachelor at Law when was ordained sub-deacon by the Bishop of Ely on 27 March 1417, deacon on 18 September 1417 and priest on 19 February 1417(8). In 1438(9) he became rector of Grasmeere in Cumberland, and on 2 December 1447 he was inducted to the rectory of Bingham, Nottinghamshire, from which, on 8 June 1448, he took a leave of absence on account of his age and infirmities, and he had resigned the living before 11 February 1450(1). The remainder of his life was passed in seclusion in Bolton Abbey in Craven, Yorkshire.

Notes:
George was a young man when he witnessed the beheading of his father in 1405, following which he was taken into the North by followers of the king, hostage to ensure the good behaviour of his family. His accounts of how Henry IV was struck with leprosy during the execution of the Archbishop became legendary.
Plumpton Correspondence page xxv - page xxvi (ed. Thomas Stapleton, 1839)
  In the year 1405 the morrow of Pentecost fell on the eighth of June, the feast of St. William of York, which is the day mentioned by Hall as that of their decollation, “on the Monday in Whitson weke.” This chronicler erroneously puts “Sir Robart” for Sir William Plumpton, and is exceeding angry with the writers and story-tellers who spread abroad that miracles were wrought at the time of the execution of Archbishop Scrope, as to the King’s being striken with leprosy, and the like. He doubtless here alludes to the History of the Martyrdom of Richard Scrope, Archbishop of York, by Clement Maidstone, where it is related, upon the authority of George Plumpton, an ecclesiastic of whom we shall speak largely in the sequel, who was an eye-witness, that on the day of the said decollation, 8th of June, great leprous pustules broke out over the said King’s face and hands, and were as prominent as the nipples of the breasts.c The vision of the son may, however, be believed to have been distorted by the recollection of his father’s execution, and by the wish, so natural to mortals, of seeing Heaven avenge our wrongs: the legendary should, at all events, have taken the precaution to look out for a more disinterested witness, before he gave publicity to the tale.
  c Anglia Sacra, vol. II. p. 369.

History of England Under Henry the Fourth vol 2 pp246-9 (James Hamilton Wylie, 1894)
In the afternoon of the day of the execution (June 8th, 1405), the King entered York and transacted some routine business. ... the King and his retinue passed through Micklegate Bar and took the road for Boroughbridge. The weather was wild, and as he rode along in the blinding rain over Hessay Moor, towards the Nidd, between Poppleton and Skip Bridge, it seemed as if some one struck him a violent blow, and as the storm did not abate, he halted at Green Hammerton for the night. Here his rest was disturbed by a hideous dream, which in the excited minds of his people became afterwards historic. It was taken by the northern folk and their clerical teachers to signify the voice of God, warning him that he should be stricken down with leprosy as a punishment for the death of the martyred Scrope. The disease was believed to have taken him inside the nose, and no doctor could ever cure it. The monk who tells the story could not make up his mind whether it came as a punishment, a warning, or an accident, so he cautiously leaves the question for God to decide. At any rate, the King called out in his sleep: “Traitors! ye have thrown fire over me.” Accommodation at a wayside Yorkshire manor would be on a homely scale, and it is likely that the sleeping-rooms were divided only by a tapet, or a parclose, of boards. Rushing up in alarm, the attendants found the light out in the King’s mortar. Thinking that he had been poisoned, they gave him a draught of vernage as a treacle, and when he rode into Ripon the next day, he was very ill (valde infirmus) and had to rest there for seven days, at the end of which time two eye-witnesses saw him (as they afterwards said), with pushes sitting like teats on his face and hands.
  One of these was Stephen Palmer, alias Cotingham, a citizen of York, the other was George Plumpton, a younger son of Sir William Plumpton, who had just been executed. He was then only a lad about twelve years of age, and had probably been retained as a hostage for the good behaviour of his family. He afterwards grew up to be a clerk of some repute, and in the two succeeding reigns, held livings and faculties suitable to the younger son of a great landed family. In course of time he told his story to Doctor Thomas Gascoigne, a nephew of the Chief Justice, who wrote an account of the events in which his uncle had played so honourable a part.
  Of the two chroniclers whose works are known to be strictly contemporary, the earlier says nothing at all about any illness, the other says in half-a-line that “immediately the King began to appear like a leper.” A third account, written at least fifteen years after, says that the King was struck with leprosy beyond the possibility of cure, on the very day and at the very hour of the Archbishop’s execution. Elmham, writing a few years after the King’s death, refers to his gracious face as horrid to all who saw it, and Waurin, about forty years later, thinks that the leprosy came immediately after his accession to the throne, as a judgment for the murder of Richard. A century later, the leading historian of England treats the whole story of the mysterious seizure as a “manifest lie,” and has some very hard words for the “foolish and fantastical persons,” the “erroneous Hypocrites and seditious Asses” who could propagate or believe it.

George was remembered in the will of his grandmother, Ellen Gisburn, dated 24 April 1408.

  *A younger son of Sir William Plumpton, and brother of Richard Plumpton, Lady de Mauley’s esquire. He was a bachelor-at-law, and was ordained sub-deacon by the Bishop of Ely in 1417. In 1438-9 he became rector of Grasmere in Cumberland, and in 1447 he was presented by Sir Thomas Chaworth to the rectory of Bingham in Nottinghamshire, which he held for two or three years, and then resigned it on account of his age and increasing infirmities. The remainder of his life was passed in the fair and secluded monastery of Bolton, and in 1459 he obtained permission from the Archbishop of York to have service celebrated for the use of himself and his servants within the walls of that monastery.
A rough translation of the Latin is:
Also, I bequeath to Master George Plompton one set of coral beads with gold gaudes.

George was an executor and feofee of, and left a bequest, in the will of his brother Richard, dated in 1443.

Plumpton Correspondence page xxxiv - page xlii (ed. Thomas Stapleton, 1839)
  George de Plumpton was, as I have already had occasion to mention, in the service of the church. To give him a title, Thomas, prior, and the convent of Landa, of the order of St. Augustin, in the county of Leicester and diocese of Lincoln, assigned him an annual pension of xli for term of life, 4 Jan. 2 Hen. IV. 1400-1;c and 3 Oct. 4 Hen. V. 1416, being then a Bachelor at Law, he had a licence from Henry, Archbishop of York and Legate of the Holy See, to receive holy orders.d Whereupon, George Plumpton, acolyte, was ordained subdeacon by John bishop of Ely, in the chapel of his manor of Dounham, in the diocese of Ely, 27 Mar. 1417;e deacon by the same prelate in the chapel of his manor of Somersham, in the diocese of Lincoln, by licence of Philip the diocesan, 18 Sept. 1417;f and priest 19 Feb. 1417-8, in the same chapel of Dounham by the same Bishop of Ely.g In 1438-9 he became rector of the parish church or free chapel of Grismere, otherwise Grassmere, in Cumberland, vacant by the resignation of Master Peter Icford, to which benefice he had been presented by the King as nominee of the abbot and convent of St. Mary’s, York, the right patrons.h On the 13th Feb. in that year, he was inducted thereto by Walter Capros, chaplain commissary of Henry Bowett, archdeacon of Richmond, in whose jurisdiction the living was situate.i In the next year (10 Feb. 1439-40), he had a faculty from Richard Arnall, sub-dean of the cathedral church of York, and vicar-general of John, Archbishop of York and Legate, to hear reserved cases in confession, and to give absolution to all penitents, save violators of the privileges of the cathedral church of York, and of the collegiates of Beverley, Ripon, and Suthwell, and breakers open of the parks belonging to the Archiepiscopal see for the taking of game therein.k In 1447 (12 Nov. 26 Hen. VI.), Master George Plompton, chaplain, had letters of institution to the rectory of the church of Bingham, in the county of Nottingham, upon the presentation of Sir Thomas Chaworth, knight, from John, Cardinal priest of the holy Roman Church, titular of St. Balbina, Archbishop of York, and Legate of the Holy See,l and was inducted by proxy 2nd December following, by the official of the Archdeacon of Nottingham.m This benefice he probably owed to the good offices of his kinsman, John Lord Scrope of Masham, Treasurer of England (26 Feb. 10 Hen. VI. 1431-2) who had intermarried with a daughter of Sir Thomas Chaworth, and whom the following letter shows to have been the patron of George de Plompton:
    To my right trusty and welbeloued Cousin, Sir William Plompton.
  Trusty and welbeloued, I greet you wel; praying you that you wil have in tendernesse and favor my welbeloued cousin George of Plompton, your nephew (rectè uncle), as towching his annuity, in such wise as he may know this my writing may turn into avail; certifiing mee wherin that I may shew you as much kindnes or ease, the which I wold do with all my hart, as God knowes, who have you in his keeping. Written at London the ninetenth day of Feveryear.
          The LORD SCROOP, tresorer of England.n
  Within a year after his taking possession of the rectory of Bingham (8 Jun. 1448), Master George Plompton had leave of absence from the diocesan for three years from that date, by reason of his increasing years and great infirmities,o during which term the rectory was let by him to farm to Sir Thomas Rempston, knight, for forty marks;p but before 11 Feb. 1450-1 he had resigned the living to Sir James Swaledale, retaining, however, a pension of xli annually for his life.q About the same time (6 Nov. 29 Hen. VI. 1450), he conveyed to feoffees, viz. the worshipfull fader and lord, Tho. Spofford, late byshop of Hereford, John Kexby, and William Middelton, clerks, and John Snaith, preist, all the lands and tenements in York and Ripon which devolved upon him after the death of his brother Richard Plumpton, to hold to the uses of his last will,r which is dated 14th November following; he thereby declared his intent to be, that they should grant the same premises “to the preist that by the grace of God shalbe made chauntery prest att the alter of Mary Magdalen in the parish kirk of Spofford in the county of York and to his successors, chauntery preists of the same; Trusting in God that I, mine executors, or some of my said welle dispozed feoffez, shall purchase and gett a licence of our soveraigne lord the King to stablish, found, create, and make a perpetuall chauntre of a preist att the aforesaid alter to serve God, and especially to pray to God for the soules of William Plompton knight and Alice his wife, my father and moder, for the soules of John Gisburgh and Ellen his wife, for my prosperity whilles I live in this world, and for my saule after I have taken the universall way, and for the saules of all them of whom said fader and mother, John Gisburgh and Ellen his wife, or I the said George, has had any goods of, and for the saules of all my fader and moder childer, and of all christen saules, Also, I will and grant, that after my decease and from the tyme that the mortsment be made of my forsaid lands and tenements to the Chauntry aforesaid, my nephew William Plompton, knight, and his heirs be the very patrons and giffers therof. Also, I will that for evermore, induring the said Chantry, my worshipfull fader and lord Tho: Spofford, late byshop of Hereford, be specially recommended in all the masses and suffrages to be done by the preste thereof, through whose good lordship and gracious favor, with great costs, I trust in God it shall come to good purpose after myne intent aforesaid.”s
  This venerable ecclesiastic passed the remainder of his life in the seclusion of Bolton Abbey in Craven; and the last memorial of him that has been preserved is a licence from John Sendale, Canon of York Cathedral, Vicar-general of William, Archbishop of York and Legate of the Holy See, for Master George Plompton to have masses celebrated in his presence in any fitting oratory within the monastery or priory of Bolton, for a year from the date thereof, viz. 4th Dec. 1459, 38 Hen. VI. with leave for his servants to hear the same.t. To him at this place the following  etter was addressed:
    To Master George Plompton at Bolton abbey.
  My best brother, I am sory by my troth that I shall nott see you, and cum thus far as to York. God knoweth my intent was not for no great gud that I thoght to desire, but I wott well now ye trusted the contrary. But. brother. it is not unknowne that I am right sickly, and my hart wold have bene gretly comforted to have spoken with you; but I trow, and so doth my daughter, that ye be displeased, denyeing that my writing afore, because she desired a booke of you. And as ever I be saved, she praied me write for either salter or primmer; and my hosband said, halfe apley, prey my brother to gett somwhat to my new chappell. God wot he ment neither gold nor silver, but some other thing for said awter. But I had knowne ye wold have bene displeased, I wold not have writt, for as much as I have speuled my best brother. My sister Dame Isabell liveth as heavy a life as any gentlewoman borne, the which cause me I faired never well sence I saw her last month. Hous such, hath nether woman nor maide with her, but herselfe alone. And her hosband cometh all day to my hosband, and seyeth the feyrest langwage that ever ye hard. But all is rong, he is ever in trouble, and all the ioy on earth hath she whan my husband cometh to her; she sweareth there is noe creature she loveth better. Also, brother, I beseech you intirely, if there be any goodly yong woman, that is a good woman of her body and pay, iiij and xx or more, (and I would have one of my owne kin an theare were any) for my selfe and deare brother, and ye or any for you can espie, I beseech you to gitt her for me, as hastely as you may, soune upon Easter, and it may be. I can no more for great hast of my jorny, but I beseech the blessed Trinitie with all the saints in heaven give me grace to se you, or I die, to Gods pleasure and your bodyly heale. And. brother, I yede to the lord Scroopeu to have sene my lady;x and be my trothe, I stood thear a large houre, and yet I might neither se lord nor ladye; ad the strangest cheare, that ever I had, of my Mistres Darse,y and yet I had 5 men in a suit: there is no such 5 men in his house, I dare say.
    Be your sister,

... the above letter, which presents a somewhat curious picture of the social habits of the time. We learn from it that an old, infirm priest had with characteristic selfishness, at a time when founding chantries for the good of souls absorbed the wealth of the dying, refused to give even a psalter or primmer to his niece, or to make any present to his brother-in-law’s chapel, and had even quarrelled with his sister for making the request. We hear also of a knight’s lady left without a single female attendant, and of an inquiry for a poor kinswoman to be hired, if she be strong and can work for her pay. And lastly, we have a Dame with five servants in her train made to dance attendance for an hour in the ante-chamber of a greater lady, and then dismissed, after receiving but strange cheer from the daughter of the house, though the parties were closely connected by ties of kindred, in fact cousins in the second degree.

There can be little doubt that Mrs. Darcy is here meant, and that it is an error on the part of the compiler of the pedigree of Scrope of Masham, illustrative of the Scrope and Grosvenor Controversy, to give Magistrix a distinct place among the children of Lord Scrope. Her husband had died young; and it appears from this letter that she passed her widowhood in the paternal mansion till the period of her second marriage with William Claxton, esq. circa 29 April, 38 Hen.

The issue of Sir Robert Plumpton and Alice Foljambe were three sons: 1. William, in his eighteenth year at the time of his father’s death; 2. Godfrey, married to Alice, daughter and coheir of Thomas Wintringham of Knaresborough, by Alice, daughter of John Dobson, before 37 Hen. VI. 1459;y 3. Robert, known only by his father’s deeds of settlement; and two daughters, 1. Joan, contracted, as is abovesaid, to marry William Slingsby, of Scriven, 21 June 1419; 2. Alice, whose alliance is doubtful: but either she or her sister became the wife of John Grene of Newby, com. Ebor. esq. previous to the 1st Jan. 5 Hen. VI. 1426-7.
 ... At the time of the marriage of his son, Sir William Plumpton was himself clandestinely married to Joan Wintringham, sister to the wife of his brother Godfrey, and who had given birth to a son; from which cause he was now seeking to effect a settlement of his lands on his heirs male, so as to give a preference to this son by the second venter over any female issue of his eldest son, should he die leaving only such surviving. ... by two several deeds of the same date, viz. 23 Aug. 31 Hen.

... Dame Isabel, her sister, whose domestic misery is so feelingly pourtrayed, was the wife of Sir Stephen Thorp of Gowsell or Goxhill, in the county of Lincoln, knight. Her marriage contract bears date 10 March, 3 Hen. VI. 1424-5 and was between Sir Robert de Hilton, kt. and Robert Constable, esq. feoffees of Stephen de Thorp, father of the said Stephen, on the one part and George de Plompton, clerk, and Richard de Plompton, esq. brothers of the said Isabella, on the other part; by it the marriage portion was fixed at 80li, and she was to be jointured to the amount of 10li per annum out of premises in the counties of York and Lincoln.a Seisin was subsequently granted to Stephen Thorp, esq. and Isabella his wife, of lands and tenements in the vills of Frismersk and Attenwyk, in the county of York, in the vill of Lednam, and in the vills and territories of Gowsell and Barowe, by Ralph Smith, chaplain, constituted (10 Oct. 4 Hen. VI. 1425) attorney for the above feoffees, and for John Dysney and John Ascyn.b He was yet an esquire, 19 Hen. VI. 1440-1;c but we have a proof that he was knighted afterward in the title of Dame given to his wife in the above letter, which presents a somewhat curious picture of the social habits of the time. We learn from it that an old, infirm priest had with characteristic selfishness, at a time when founding chantries for the good of souls absorbed the wealth of the dying, refused to give even a psalter or primmer to his niece, or to make any present to his brother-in-law’s chapel, and had even quarrelled with his sister for making the request. We hear also of a knight’s lady left without a single female attendant, and of an inquiry for a poor kinswoman to be hired, if she be strong and can work for her pay. And lastly, we have a Dame with five servants in her train made to dance attendance for an hour in the ante-chamber of a greater lady, and then dismissed, after receiving but strange cheer from the daughter of the house, though the parties were closely connected by ties of kindred, in fact cousins in the second degree.

Some sources (see Magna Carta Ancestry 2nd ed. p258 (Douglas Richardson, 2011)) postulate a second husband of Isabell, William Bukton, of Banningholme, Yorkshire. In his will dated 1443 (Plumpton Correspondence page xxxiv (ed. Thomas Stapleton, 1839), Isabell's brother, Richard, leaves a bequest to "Dame Isabella de Bukton a capital gold ring with two images." although he does not state his relationship to this Isabella. The very next bequest in the will is to "Katherine, my sister, a gold cross.". If Isabell de Bukton is correctly the former Isabella (Plumpton) Thorpe, then that is also a good explanation of why she is referred to in Katherine's letter to her brother George in the 1450s, as "my sister Dame Isabell" which others have taken to mean that Stephen Thorpe was knighted.

  SIR WILLIAM MALLORY. The statements in the deposition of this Knight, relative to the arms of Sir Robert Conyers being in a chapel at Houghton Conyers in Yorkshire, is explained by his pedigree. His grandfather, Sir Christopher Mallory, married Joan the daughter and heiress of Sir Robert Conyers of Houghton Conyers, with whom he acquired that property: their eldest son, Sir William Mallory, of Houghton Conyers and Studley,1 married Katherine daughter and coheiress of Sir Ralph Manwycke or Nonwyke,2 who was living in 1421, and by her had the deponent.1 He married Joan daughter of Sir William Plumpton,1 2 and died before 1421, as in that year Katherine his mother granted lands in Houghton upon the death of Joan his widow.1 William Mallory, his son and heir, appears to have been the Sir William Mallory, Knight, who received letters of protection in consequence of being abroad in the King’s service in April 1417, and again in May 1430:3 he left descendants.1
  Sir William Malore, aged thirty four, armed sixteen years and upwards, said that the arms Azure, a bend Or, had always belonged to Sir Richard Scrope and his ancestors, and never heard to the contrary; that he saw Sir Richard so armed in the expedition of the Lord of Lancaster throughout France, and in Scotland with his banner with the said Lord of Lancaster, and also saw him there lately with the King, as well as others of his name and lineage so armed with differences as branches of his family. He also said, that at Houghton Conyers, where he resided, there was a chapel of ancient structure ordained for certain priests of a chantry, in which chapel were painted the arms of Scrope, Azure, a bend Or, and the arms of Sir Robert Conyers and Sir Simon Warde, which had been there depicted from the time of the building of the chapel, which was beyond the memory of man. He had heard brave and gallant men, old knights and esquires of the North, say that the said Sir Richard had full right to bear the said arms, which had descended to him from the time of the Conquest, as he had heard from his ancestors and from other valiant persons then deceased. He had never seen or heard of Sir Robert Grosvenor or of his ancestors, before the commencement of the controversy.

Joan (Plumpton) Grene

Father: Robert Plumpton

Mother: Alice (Foljambe) Plumpton

Married: John Grene

This marriage had occurred by 20 October 1423, when a grant mentions John and Joan as married.

John was the son of Richard Grene, of Danby, Yorkshire, and Margaret. He was steward to his brother-in-law, Sir William Plumpton. John Grene "de Nuby" was a feofee of two feoffments made by his father-in-law, Sir Robert Plumpton, on 6 November 1416 (Plumpton Correspondence page xlv) and 24 September 1420 (Plumpton Correspondence page xlvii). At the time of the first feoffment, and a further instrument dated 1 April 1418 it is clear that Joan is yet unmarried, but it is unclear whether or not he was married to Joan by the date of the seconf feoffemnt. John had died by 28 May 1462, when he is described as "the late John Grene" in a lawsuit involving his nephew, Richard Grene.

Notes:
Joan was contracted to marry William Slingsby of Scriven, Yorkshire, on 21 June 1419 (Plumpton Correspondence page xlvii (ed. Thomas Stapleton, 1839)), but it is unclear if this marriage actually took place. Joan was definitely married to John Grene by 20 October 1423.
There are various confusing and contradictory accounts of William's parents, who he actually married and possible children found in Visitation of Yorkshire made in the years 1584/5 p113 (Robert Glover, 1875), Dugdale's Visitation of Yorkshire, with Additions parts 5-7 p65 (William Dugdale, 1901), The Diary of Sir Henry Slingsby pp391-2 (Henry Slingsby, 1836) and The Family of Coghill 1377 to 1879 p165 (James Henry Coghill, 1879).

  My best brother, I am sory by my troth that I shall nott see you, and cum thus far as to York. God knoweth my intent was not for no great gud that I thoght to desire, but I wott well now ye trusted the contrary. But. brother. it is not unknowne that I am right sickly, and my hart wold have bene gretly comforted to have spoken with you; but I trow, and so doth my daughter, that ye be displeased, denyeing that my writing afore, because she desired a booke of you. And as ever I be saved, she praied me write for either salter or primmer; and my hosband said, halfe apley, prey my brother to gett somwhat to my new chappell. God wot he ment neither gold nor silver, but some other thing for said awter. But I had knowne ye wold have bene displeased, I wold not have writt, for as much as I have speuled my best brother. My sister Dame Isabell liveth as heavy a life as any gentlewoman borne, the which cause me I faired never well sence I saw her last month. Hous such, hath nether woman nor maide with her, but herselfe alone. And her hosband cometh all day to my hosband, and seyeth the feyrest langwage that ever ye hard. But all is rong, he is ever in trouble, and all the ioy on earth hath she whan my husband cometh to her; she sweareth there is noe creature she loveth better. Also, brother, I beseech you intirely, if there be any goodly yong woman, that is a good woman of her body and pay, iiij and xx or more, (and I would have one of my owne kin an theare were any) for my selfe and deare brother, and ye or any for you can espie, I beseech you to gitt her for me, as hastely as you may, soune upon Easter, and it may be. I can no more for great hast of my jorny, but I beseech the blessed Trinitie with all the saints in heaven give me grace to se you, or I die, to Gods pleasure and your bodyly heale. And. brother, I yede to the lord Scroopeu to have sene my lady;x and be my trothe, I stood thear a large houre, and yet I might neither se lord nor ladye; ad the strangest cheare, that ever I had, of my Mistres Darse,y and yet I had 5 men in a suit: there is no such 5 men in his house, I dare say.
    Be your sister,

   The writer of this letter, Katharine Chadyrton, was the younger of the two daughters of Sir William Plumpton, kt. by Alice Gisburne, who yet remained unmarried at the time of their mother’s death in 1423. Her husband, it may be presumed, was of the family of Chadderton of Chadderton Hall, in the chapelry of Oldham in Lancashire; but their pedigree is unknown to me, and the Plumpton evidences are unfortunately here of no assistance.
... the above letter, which presents a somewhat curious picture of the social habits of the time. We learn from it that an old, infirm priest had with characteristic selfishness, at a time when founding chantries for the good of souls absorbed the wealth of the dying, refused to give even a psalter or primmer to his niece, or to make any present to his brother-in-law’s chapel, and had even quarrelled with his sister for making the request. We hear also of a knight’s lady left without a single female attendant, and of an inquiry for a poor kinswoman to be hired, if she be strong and can work for her pay. And lastly, we have a Dame with five servants in her train made to dance attendance for an hour in the ante-chamber of a greater lady, and then dismissed, after receiving but strange cheer from the daughter of the house, though the parties were closely connected by ties of kindred, in fact cousins in the second degree.

There can be little doubt that Mrs. Darcy is here meant, and that it is an error on the part of the compiler of the pedigree of Scrope of Masham, illustrative of the Scrope and Grosvenor Controversy, to give Magistrix a distinct place among the children of Lord Scrope. Her husband had died young; and it appears from this letter that she passed her widowhood in the paternal mansion till the period of her second marriage with William Claxton, esq. circa 29 April, 38 Hen.

Birth: about 1341

Father: William Plumpton

Mother: Christiana (Moubray) Plumpton

Plumpton Correspondence footnote to page xxii (ed. Thomas Stapleton, 1839)
the writer of the same notice [Controversy between Sir Richard Scrope and Sir Robert Grosvenor in the Court of Chivalry, royal 8vo, 1832. By Sir N. Harris Nicolas, K. H. vol. I. p. 270] thinks it most probable that Sir Robert was the issue of his father’s first marriage with Alice Byaufiz; but, letting alone the proof to be derived from his age at the time of the controversy, it is also certain that the manor of Brakenthwaite, with the lands which were of the inheritance of Alice, reverted, agreeably to the limitation in the fine noticed in the text, to the posterity of Thomas, son of Peter de Midleton, which could only be in case of failure of issue of Alice. (Plumpton Evidences.)

Married (1st): Isabella Scropes

Isabella was born on 24 August 1337, the daughter of Henry first Lord Scrope of Masham, and his wife, Joan. She was the sister of Richard Scrope, Archbishop of York, alongside whom her son, William Plumpton, was executed in 1405.

II. 1399, “Isabella quondam vocata de Kirkoswald.”

Isabella married, secondly, Sir Nicholas Middleton, as his third wife, in 1413.
Ilkley: Ancient & Modern pp80-1 (Robert Collyer, 1885)
  Sir Nicholas Middleton, son of Sir Thomas, was born in 1348, the blackest year of the Black Death, but this is all we can learn about him until 1378, when he is thirty years of age, unmarried, and living at Stubham. He was married three times, however, despite this touch of hesitation at the start—(1) to Matilda, daughter of Sir Robert de Veteripont, (Oldbridge) (2) to Avice [Aniste de Stapilton], who bore him a son and heir, and (3) to Dame Isabel, widow of Sir Robert Plumpton—his third marriage taking place in 1413, when he was 65 years old.
  There was some trouble with the Church about this third marriage, for Archbishop Bowet—that jolly old dignitary, who built a noble new kitchen to his manor house at Otley, and managed there and otherwheres to consume four-score tuns of claret every year—was moved to request Richard Pitts, his Vicar General, to inquire into a dispensation which had been granted to Sir Nicholas Middleton and Dame Isabel Plumpton, who wanted to marry, and were related in the third and fourth degrees. We may note also that Sir Nicholas was one of the feoffees of the manor of Plumpton, under the will of this Sir Robert, who died on the 19th of April, 1407, and that the widow’s jointure under this trust was only fifty marks a year, so that the old knight, it is evident, did not marry the lady for her money, and he was himself one of the richest men in the West Riding. His name appears, in 1384, as a witness to the will of Sir Brian Stapilton, in which he was also a legatee—“Item jeo devise monsieur Nicholl de Medilton j nowche enveronne de perill, oue mon corne que j’ay solay porter pour le cuspell.”* In 1386 he stands as a witness to a deed by which Richard, son of John Mason, of Draughton, gives Drystones and Risphill to Sir Peter Mauleverer, of Beamsley. He holds the manor court also at Stubham, at Martinmas, 1400, and again in the April following. In 1410 he was made Commissioner of Array for the West Riding, for trouble was brewing as usual in Scotland, was still alive in 1416, three years after his third marriage, and spending his halloween with dame Isabel, but in 1420 he was dead.  

Occupation: Knight
Robert had been under arms for twenty-fours years when he was deposed in the Scropes controversy in 1386, and participated in military expeditions in France and Scotland. He was appointed lieutenant of the forest of Knaresborough in May 1387, and was constable of the castle of Knaresborough.

Notes:
The first reference I find to Robert as a knight (or 'chivaler' ) is on 22 September 1372.

The Controversy between Sir Richard Scrope and Sir Robert Grosvenor vol 2 pp310-2 (N. Harris Nicholas, 1832)
    DEPONENTS IN FAVOUR OF SIR RICHARD SCROPE.
  SIR ROBERT PLUMPTON. The ancient family of which this knight was the representative had been seated at Plumpton in Yorkshire for many generations. His father Sir William Plumpton was twice married: first to Alicia daughter and heiress of Sir Henry Beaufitz; and secondly to Christiana Monasby, or Mowbray,1 widow of Richard de Emeldon;2 but pedigrees differ as to which of these women was the Deponent’s mother, though it is most probable that he was the issue of the first marriage.3
  Sir Robert was born about 1341, and appears from his deposition to have repeatedly served in the wars of his time. He was in the King’s fleet in 1372, and was permitted to return to England, on account of a severe illness, with his esquire and two valets.4 In May 1387 he was appointed Lieutenant of the forest of Knaresborough,1 and died in the 8th Hen IV 1406-7.5 He was twice married: first to Isabella daughter of Henry first Lord Scrope of Masham, who was born in 1337,6 and died before 1399; and secondly to Isabella de Kirkswold, who took to her second husband Sir Nicholas Middleton.1 3 By Isabella Scrope, Sir Robert had a large family. Sir William Plumpton, their eldest son, joined the conspiracy of his uncle Richard Scrope, Archbishop of York, and shared that prelate’s fate, he having been beheaded at York on the 8th June 1405.7 By Alice, who died in 1423, daughter and coheiress of John Gisburne, citizen and merchant of York, he had eight children: namely, Robert; Thomas and Bryan, who both died without issue; Richard, who made his will in 1443; George, who was rector of Bingham; Joan, who died before her mother without issue; Katherine, who was living unmarried in 1443; and Isabella, who married Stephen de Thorpe of Gowsill, Esq. on the 10th March 1425.1 Sir Robert Plumpton, the eldest son of Sir William and Alice Gisburne, was found heir to his grandfather in the 8th Hen. IV., at which time he was twenty-four years old, and was the ancestor of Robert Plumpton of Plumpton, who was of full age when the pedigree was entered at the Heralds’ Visitation of Yorkshire in 1665.
  Sir Robert Plumpton, aged forty-five years, deposed that he had seen Sir Richard Scrope with the arms Azure, a bend Or, and his cousins so armed with differences; that he saw Sir Richard armed in these arms entire, and Sir Henry Scrope with the same arms differenced by a white label publicly borne on his banner in France, before Paris and elsewhere, in presence of the late noble King and other great lords of England. He saw also the said Sir Richard twice in Scotland armed in the same arms, and with his banner, in presence of the King and the Duke of Lancaster; and in all the expeditions and journeys in which the Deponent had been for the twenty-four years during which he had been armed, he had seen the said Sir Richard or his cousins armed in like manner with differences. The Deponent further said, that the arms in question belonged of right to the said Sir Richard, having descended to him from his ancestors, as he had heard from his ancestors, and as fully appeared by the tombs of ancestors of the said Sir Richard who lie interred in the Abbey of St. Agatha with those arms over them. He added, that Sir Richard and his ancestors had been in possession of these arms from the time of the Conquest, without interruption from Sir Robert Grosvenor, or any other of his name, as he had heard from many valiant knights, and as common fame testified.
  The arms of Sir Robert Plumpton were, Azure, five fusils conjoined in fess Or, each charged with an escallop Gules.2

Plumpton Correspondence page xxi - page xxvi (ed. Thomas Stapleton, 1839)
[Sir William Plumpton] died 36 Edw. III. 1362, towards the close of the year, as appears by the account of the feodary of the honour of Pontefract of that date, wherein is set down xxvs. as the relief of Robert de Plumpton, knight, for the fourth part of one knight’s fee in Idell, after the decease of William de Plumpton, knight, his father.x
  Sir Robert de Plumpton was a deponent in the Scrope and Grosvenor controversy on the 17th day of September 1385, being then of the age of forty-five years, which places his birth in the year 1341, and consequently posterior to his father’s second marriage.y He appears from this deposition to have repeatedly served in the wars of his time. In 1372 he had gone on board the King’s fleet, but falling suddenly and dangerously ill, and being unable to continue this sea voyage, he was compelled to go ashore at the town of Rye; whereupon the circumstances of his case having first been returned into the Chancery under the seal of Simon Burgh, Constable of Rochester Castle, a writ was sent to the mayor and bailiffs of the town to exonerate him from blame, and instructing them to allow him, with John Heton, his esquire, and his two valets, to return home with all his equipage unmolested.z 
In the reign of Henry the Fourth, Sir William Plumpton, the eldest son of Sir Robert Plumpton, suffered death upon a scaffold for the part he took in the insurrection stirred up by his uncle Richard, Archbishop of York, whose sister, Isabella Scrope his father had married.
 ... No act of attainder followed upon the execution of the rebels, and Sir Robert Plumpton, the father, obtained for himself a general pardon for all treasons and felonies; to which effect I find letters patent from the King, bearing date at Newcastle-upon-Tyne, 21 June, 6 Hen IV, 1405.d He died 19 April, 8 Hen. IV. 1407,e having by his will, dated 26th of February preceding, directed his feoffees, Sir William Gascoigne and Sir Nicholas de Middelton, knights, Richard de Kendale and William de Authorp, parsons of the churches of Ripley and Dighton, to grant the manor of Plompton to Isabel “ma trescher compaigne” for her life, with remainder to Robert son of William de Plompton, son neveue, in fee, so as to secure to his relict a yearly jointure of fifty marks.f This lady was his second wife, and was of Kirkoswald in Westmoreland,g she being styled in the deed securing to her a future settlement, bearing date 12 July, 23 Ric. II. 1399, “Isabella quondam vocata de Kirkoswald.” Of Isabella Scrope, daughter of Henry first Lord Scrope of Masham, the first wife of Sir Robert Plumpton, mention has been made.

  y See Controversy between Sir Richard Scrope and Sir Robert Grosvenor in the Court of Chivalry, royal 8vo, 1832. By Sir N. Harris Nicolas, K. H. vol. I. p. 270.—In the biographical notice, it is said that Sir Robert Plumpton was appointed lieutenant of the forest of Knaresborough in May 1387; the original authority for which assertion was doubtless the following charter, numbered 363 in the Cartulary:
   Johan de la Pole, cheif senescall de mon tres redoute Sire, le Roy de Castell et de Leon, duc de Lancastre, de North Trent, a Monsr Robert de Plumpton, lieutenant del Meistre Forestier de la forest de Knaresburgh, salutz. Vous mande et charge de par mon dit Sire que vous faciez delivrer a Johan Brown de Knaresburgh un Stubb pur merasme, apprendre deinz la foreste illoeqez, pur edifier une meeson sur la terre de mon dit Sire, quil tient par terme des ans a volunte, en la ville de Knaresburgh. Et auxint facez delivrer a William Clerc de Knaresbrough un Stubb pur merisme, apprendre deinz la forest suisdite, pur reparacion des mesons affaire sur la terre de mon dit Sire en la dite ville. Et ceste ma lettre vous ent sera garrant. Escrit a Knaresburgh, le viij jour de Maij, lan du Regne le roy Richard secound puis la conqueste, disme. (8 May, 10 Ric. II. 1387.) Number 291 in the same Cartulary is a copy of a bailbond from John son of Robert de Knaresburgh, and John de Makelay of Scotton, to Sir Robert de Plumpton, Constable of the castle of Knaresburgh, dated at Knaresburgh, 26th of October, 11th Ric. II. (1387); but the exact date of his appointment to these lieutenancies is not apparent from either document. In the same memoir he is likewise stated to have had a large family by his wife, Isabella Scrope, whereas Sir William Plumpton was the only son, and there is no evidence as to female issue. Again, the writer of the same notice thinks it most probable that Sir Robert was the issue of his father’s first marriage with Alice Byaufiz; but, letting alone the proof to be derived from his age at the time of the controversy, it is also certain that the manor of Brakenthwaite, with the lands which were of the inheritance of Alice, reverted, agreeably to the limitation in the fine noticed in the text, to the posterity of Thomas, son of Peter de Midleton, which could only be in case of failure of issue of Alice. (Plumpton Evidences.) It was in right of this descent that the Midletons of Stockeld quartered the coat of Plumpton, that is, of the seneschals of Plumpton.

Fraser's Magazine for Town and Country vol 56 p225 (1857)
1372, in which year Sir Robert went on board the king’s fleet, and being suddenly taken dangerously ill, was obliged to put ashore at Rye. His courage and loyalty were prevented from being called in question by his sending to the Court of Chancery an account—to which the sign manual of Simon Burgh, the constable of Rochester Castle, was attached—of the unfortunate circumstances of his case. The statement was favourably received, and a writ was sent to the mayor and bailiffs of Rye, declaring him free from blame, and requiring that he should be permitted to return home unmolested.
  Fortunate as the Plumpton family generally were, they did not always escape the strokes of an adverse fate. Thus William, son and heir of Sir Robert, suffered death on the scaffold in the reign of Henry IV., for the part he had taken in the insurrection set on foot by his uncle, the Archbishop of York. ... In this instance Henry did not visit the sins of the criminal upon his relatives, for Sir Robert obtained, after his son’s execution, a sweeping pardon for all treasons and felonies by him committed. He died two years afterwards, leaving to Isabel, his wife and tres cher compagne, the manor of Plumpton for her life, with the remainder to his grandson Robert, son of William de Plompton. 

History of England Under Henry the Fourth vol 2 p210 (James Hamilton Wylie, 1894)
When the new King was at York, in the summer of 1400, the Archbishop did all he could to assist him in raising money for his expedition against the Scots, but his interest went less with Bolingbroke than with the Percies and, so far as he dared, he lent his influence to all their plots and intrigues. His elder sister, Isabel, was married to Sir Robert Plumpton, a wealthy tenant of the Percies, near Spofforth

Robert Plumpton

Birth: 1382/3
Robert was 24 years old at his grandfather's IPM on 30 May 1407.

Father: William Plumpton

Mother: Alice (Gisburn) Plumpton

Married: Alice Foljambe
The marriage contract was signed on 14 January 1392(3), when both parties were still children.

Alice was the daughter and heir of Godfrey Foljambe
Alice (1387-bef. June 1419), da. and h. of Sir Godfrey Foljambe (1367-88) of Ockbrook, Derbys. and Mansfield Woodhouse, Notts. by Margaret (d. Apr. 1454), da. of Sir Simon Leek†, at least 3s. inc. Sir William†, 2da. Kntd. by Oct. 1411.2  (from http://www.historyofparliamentonline.org/volume/1386-1421/member/plumpton-sir-robert-1383-1421). In an agreement signed by Robert Plumpton concerning the marriage of his son William dated 20 January 1415-16, mention is made of "Dame Alice his late wife".

The Old Halls, Manors and Families of Derbyshire vol 1 p228 (Joseph Tilley, 1892)
Alice, his daughter and heir, being at the time of his decease, little more than a year old. By a subsequent writ, tested at Westminster 16 February, thirteenth of his reign, King Richard granted to the said Sir John Leeke the marriage of the heiress for fifty marks, which wardship of marriage he, by indenture, dated at Downham-upon-Trent on the morrow of St. Hilary, 16 Richard II., 1392-3, transferred to Sir William Plumpton, Knight, to the intent that she should be matched with his son and heir apparent whomsoever he should be, in consideration of a hundred marks, and upon condition of other annual sums till she reached the age of fifteen years. The marriage took place, and, after the completion of her fourteenth year, Robert Wycard, the King’s escheator for the county of Derby, delivered seisin to William de Hardelsey, attorney of Robert de Plompton, and Alice, his wife, daughter and heir of Godfrey Foliamb. Ch’r of all lands of which the said Godfrey was seised in demesne as of fee on the day he died, and attested the fact by the deed dated at Chaddesden on Sunday next before the feast of St. Nicholas bishop, 3d of Hen. IV. (4 Dec. 1401).

Children: Occupation:
Robert was a Member of Parliament representing Yorkshire in 1411, Nottinghamshire in April 1414 and Yorkshire in March 1416. On 15 October 1415, he was retained to serve the John of Lancaster, Duke of Bedford, brother of the Henry V, for life, in peace and in war, being paid 20 marks as his fee in time of peace, and the usual wages suitable to his degree in time of war, together with bouche du courte (supplied food) for himself, an esquire, and his two valets, when at the hostelry of the Prince, or in his company. This was an interesting appointment, considering that Robert's father had been executed for treason against Henry IV, the duke's father. In 1416, Sir Robert de Plompton was steward of the Forest of Knaresborough, as well as seneschal of the Honour of Knaresborough.

  To William Rempston escheator in Notynghamshire. Order to give Robert Plumpton and Alice his wife, daughter and heir of Godfrey Foljaumbe knight (chivaler) son of Godfrey son of Godfrey Foljaumbe knight (militis) seisin of the lands of the said knight (militis), which came to the late king’s hands by his death and by reason of the nonage of the said knight (chivaler), who died within age in ward of the late king; as she has proved her age before the escheator, and the king has commanded the abbot of Fountains to take the fealty of the said Robert.

On 21 June 1405, Robert was pardoned by the king for all "treasons, insurrections, rebellions and felonies" committed by him. Presumably this was related to the treason for which his father had been executed.

  Robert de Plumpton, nephew and heir, was twenty-four years old at the time of his grandfather’s death, and yet an esquire. By intermarrying with the heiress of Sir Godfrey Foljambe, knight, whose marriage had been contracted for in his father’s lifetime, he added greatly to the wealth and importance of his family, by the acquisition of large estates in the counties of Nottingham and Derby. His mother was Alice, daughter of John Gisburn, citizen and merchant of York, and coheiress with Isabel, wife of Sir William Frost, kt. to their father. After the death of her unfortunate husband, she made the following agreement with her son Robert.

  To return to Sir Robert Plumpton. He was a knight before the 15th Jan. 1410-1, 12 Hen. IV. when he made a feoffment of his estates in Yorkshire to Henry Lord Fitzhugh, Sir Richard Norton, William Ferman, rector of the church of Kirkby Oreblawer, and Richard Sudberi, rector of the church of Croston;d and as such was chosen to represent the shire of York in the Parliament which met on the 3d November, 13 Hen. IV. 1411. In the same reign (1 July, 13 Hen. IV.) I find a grant by Henry Beaufort, Bishop of Winchester, of an annual rent of xxli sterling out of his manor of Whitteny, in the county of Oxford, pour le bon et greable service que notre trescher et tres bien amé Monsire Robert Plumpton chevaler ad fait et ferra en temps avenir.e In 2nd Henry V. (14 Oct. 1414) Sir Robert Plumpton was Seneschal of the Honour of Knaresborough, as also one of the Council of the King of his Duchy of Lancaster, together with Sir Roger Leche, knight, Chief Seneschal of the lands of the King of his Duchy of Lancaster towards the north part and elsewhere.f In 3d Hen. V. (15 Oct. 1415), he was retained to serve the Duke of Bedford for life, in peace and in war, having xx marks as his fee in time of peace, and the usual wages suitable to his degree in time of war, together with bouche du courte for himself, an esquire, and his two valets, when at the hostelry of the Prince, or in his company.g
  On the seventh of October, the feast of St. Marcus, Pope, 6 Hen. IV. 1404, Sir Robert Plumpton had born to him a son and heir,h afterward Sir William Plumpton, knt. and the same with whose correspondence the series of letters commence. Of this son, when in his twelfth year, the marriage was contracted for on the part of Sir Bryan de Stapilton, of Carlton, com. Ebor. knight, in behalf of his daughter Elizabeth, an infant of the same tender years. The agreement bears date 20 Jan. 3 Hen. V. 1415-16; thereby Sir Bryan accords, that a sum of CCCLX marks be paid to Sir Robert Plumpton for the marriage, he agreeing to settle an estate of xx marks yearly in the vill of Kinalton on his son William and Elizabeth, and their issue. He was further to engage to make a feoffment to Sir Richard Redmayn, knight, John de Moute, esq. Robert Brame and Roger Spofford, chaplains, of the manor of Steton, to secure a rent-charge of XL marks yearly, in case that if the said William and Elizabeth were legally ousted of the estate in Kynalton by Sir Robert or his heirs, or the heirs of Dame Alice his late wife, then the feoffees to convey the same to William and Elizabeth. Within a month after the death of his mother, Dame Alice de Plumpton, Sir Robert was to add x marks to the yearly rent out of Kynalton, except in case Dame Margaret Rempston or Thomas Foljambei pre-deceased his mother, or that she herself happened to die during the minority of her grandson William. There were beside covenants for re-payment of the principal, in case of either of the parties dying without issue, or of divorce before consummation, as well as of a further sum of L marks for the costs of their maintenance. It was also stipulated that Sir Robert de Plompton should not make any feoffment or estate to the disinherison of the said William, his son, of the land which he held, either by descent, or curtesy after the death of Dame Alice his late wife; save only he might give rent-charges of xx marks each to his two younger sons Godfrey and Robert, with right of mutual accretion in case of either of them being promoted to a benefice, or advantaged by marriage, and of survivo ship in case of death. Also, he might jointure any future wife he might take to himself, so as the jointure did not exceed C marks. Sir Bryan de Stapilton and Dame Agnes his wife were to have the governance of the said William and Elizabeth during their minority, receiving for their sustenance the rent of xx marks out of Kynalton; but in case Sir Bryan should happen to die, and his widow take a second husband, then Sir Robert was to have the govern ance of the betrothed parties.k
  In 1416, 4 Hen. V. Sir Robert de Plompton was Steward of the Forest of Knaresborough, as well as Seneschal of the Honour.
  “Unto the worshipfull and reverent Sir, Monsire Robert de Plompton, steward of the forest of Knaresburgh, or to his deputies, William Bedale, mercer, Richard Bellingham, mercer, John Unthank, spicer, William Garnet, bower, Tho: Constable, fletcher, and Tho: Lincolne, Citizens of York, send honor and reverence; for als mekill als an John of Lawe, chapman, sold unto Richard Clerk of Burebrig a pak with divers mercery therein and a horse for xxie nobles of the Kings coyn, on thursday next after St. Elen day last past, in the towne of Burebrig, als wee are fully by true men enformed: and for als mekill als it is needfull and necessary thing to all christen men to record and beare witness o’ the soth, we do ye to witt that the gude quilk the foresaid John sold att Burebrig was his awen proper gude, and lelely and truly bought and sold, and a gude man of name and fame evere zhit was and is halden amang us, and for na nother nevere zhit was halden ne reccond. And this witnesse we by this our present letter, written and seald att Yorke, the xxiiij day of May in the yeare of King Henry fift after the conquest of England, fourth.”l
  Sir Robert de Plompton made a further feoffment of all his manors and reversions in Yorkshire to Henry Fitzhugh, lord of Ravenswath and Treasurer of England, Dame Margaret de Rempston, Dame Alice de Plumpton his mother, John Grene de Nuby, William Ferman parson of the church of Kirkby Orblawers, and John Brennand of Knaresburgh, on the 6th November 1416;m the purport of which feoffment, by an instrument dated at Plumpton, 1 April, 6 Hen. V. 1418, was declared to be for securing to Godfrey and Robert de Plumpton their annuities of xx marks each; and if it should so fall out that he the said Sir Robert de Plumpton, knight, should die before his coming into England, the residue was to be applied according to the directions in his last will. The said feoffees were also to marry his daughters Joan and Alice suitably, and to give xl marks to his sisters Isabella and Katharine for their marriage, and xls yearly to his brother Richard out of the manor of Nesfield near Addingham.n On the 11th day of the same month of April, I find Sir Robert de Plumpton was to be at the muster at Southampton pour le viage notre Sire le Roy de vers son Roialme de France, in the retinue of the Lord Fitzhugh;o and as about to go abroad, he had the usual letters of protection from the Duke of Bedford, Guardian of England, tested at Southampton 29th of the same month.p On the 21st of June, 7 Hen. V. 1419, while yet abroad, he contracted for the marriage of Joan his daughter to William Slingsby of Scriven, in com. Ebor. esq., Sir Thomas Rempston, kt. his brother-in-law (son of Dame Margaret Foljambe, mother of Alice, Sir Robert’s deceased wife, by her second husband, Sir Thomas Rempston, K.G.) being also a covenanting party on her behalf.q
  Sir Robert Plumpton was again in England before 27th Aug. following;r and on the 24th Sept. 8 Hen. V. 1420, he enfeoffed Dame Alice de Plompton his mother, Richard de Norton, Chief Justice of the Common Bench, Thomas de Rempston, ch’r, John Butler, esq. and John Grene, in his manors of Plompton, Idill, Steton in Aierdale, and Nesfeld, with the advowson of his chantry of the Holy Trinity in the church of Ripon, in com. Ebor., and in the reversions of a rent-charge of four marks, issuing out of the manor of Plompton, which Dame Isabell, late wife of Sir Robert Plumpton, kt. his grandfather, had of his grant for term of life in lieu of dower, and of the manors of Gersington in Craven, and Little Studley, after the decease of Alice his mother.s But the following indenture shows him to have been at Portsmouth, with archers in his retinue, on the 12th Oct. next ensuing, on his route to cross the sea on an expedition into France.
  “This indenture, made the yeare of our soveraigne Lord King Henry the Vth after the Conquest the viiith, betwixt Robert of Plompton, knight, of the to party; John Fleetham, Tho. Clerke, William Chamberlaine, Robert Barden, Henry of Ripley, Robert Morton, William Cowper, Hugh Coke, of the tother party; beares witnesse that the foresaid John, Tho.

  In the following year, as we learn from an Inquisitio post mortemu and from the epitaph on his monument in the church of Spofforth, Sir Robert Plumpton died. It was a tradition in the family that he was slain in France, his death occurring abroad at the time of the siege of Meaux; but the epitaph reads simply,
  “Hic jacet Robertus Plumpton, mil. nuper Senescallus de Knaresborough, et Alicia uxor ejus, filia & heres Godfridi Foljambe, mil. qui Robertus obiit 8 Decembris 1421, quorum animabus propitietur Deus.”x
  The issue of Sir Robert Plumpton and Alice Foljambe were three sons: 1. William, in his eighteenth year at the time of his father’s death; 2. Godfrey, married to Alice, daughter and coheir of Thomas Wintringham of Knaresborough, by Alice daughter of John Dobson, before 37 Hen. VI. 1459;y 3. Robert, known only by his father’s deeds of settlement; and two daughters, 1. Joan, contracted, as is abovesaid, to marry William Slingsby, of Scriven, 21 June, 1419; 2. Alice, whose alliance is doubtful: but either she or her sister became the wife of John Grene of Newby, com. Ebor. esq. previous to the 1st Jan. 5 Hen. VI. 1426-7.

  128. ROBERT PLUMPTON.  Nov. 1411, co. York; Apr. 1414, co. Notts.; Mar. 1415/6, co. York.
  Robt Plumpton was the great-grandson of the Wm de Plumpton of whom a notice appears above, being the s. of Wm Plumpton—s. of Robert, s. of the kt of sh.—by his wife Alice, dau. and coh. of John Gisburn, citizen and merchant of York. His father joined abp Scrope’s rebellion and was beheaded on 8 Jun. 1405, and in Apr. 1407, young Robt succeeded to his grandfather’s estates, being at that time 24 yrs old.13 He mar. Alice, dau. and h. of Godfrey Foljambe. The marriage was arranged before 14 Jan. 1392/3, and had taken place before the couple inherited Godfrey’s lands in 1401.1 Their s. and h. Wm was b. on 7 Oct. 1404, and on 20 Jan. 1415/6, was contracted to marry Eliz., dau. of Sir Brian Stapilton of Carlton.2 Robt was ktd before 1411, and d. on 8 Dec. 1421, being bur. at Spofforth ch.3
  He inherited the mans. of Steeton, held of the earl of Northumberland, but in the Kg’s hands by reason of the earl’s forfeiture; Idel, held of the honour of Pontefract, of the duchy of Lancaster; and Nesfield;4 while his wife brought to the family lands in cos. Notts., Derby, Warwick, and Leicester.5
  On 21 Jun. 1405, Plumpton received a pard. of treason and felonies, referring presumably to some part in the rebellion which his father had joined with fatal results.6 His name appears in the W.R. comm, of array of 5 Jul. 1410,7 and he rep. co. York in the parl. of Nov. 1411,8 during the session of which he was appd on a comm, of o.t.9

Oxford.10 In the parl. of Apr. 1414, Plumpton rep. Notts.11 On 14 Oct. 1414, he was one of those commd to arrest various persons living in the parishes of Knaresborough, Pannal, Hampsthwaite and Ripley, and take them into Chanc., whither they had been summd by writs which they had not obeyed.12 He was retained for life to serve John, duke of Bedford, in peace or war, on 15 Oct. 1415.13
  Plumpton was again retd for co. York to the parl. of Mar. 1415/6, his colleague on this occasion being Brian Stapilton,14 with whom he had shortly before made the marriage contract mentioned above. About this time Plumpton was steward of the honour and forest of Knaresborough.15 In Apr. 1418, he appeared at the muster at Southampton for the exped. to France, in the retinue of lord FitzHugh, and was still abroad on 21 Jun. but retd before 27 Aug.1 On 26 Nov. 1419, he was constituted a commr for raising the loan in the W.R.2 He was at Portsmouth ready to go abroad again in Oct. 1420, when he engaged eight archers to go with him.3 Tradition has it that he d. before the walls of Meaux, but this is not mentioned in his epitaph.4

Death: 8 December 1421, by family tradition at the siege of Meaux, France, although he was buried in England

PLUMPTON, Sir Robert (1383-1421), of Steeton, Yorks. and Kinoulton, Notts. in The History of Parliament: the House of Commons 1386-1421 (ed. J.S. Roskell, L. Clark, C. Rawcliffe., 1993)
Sir Robert returned to the theatre of war in October 1420, when he left Portsmouth with a private retinue of eight archers who were to fight under his command in the royal army for the next year. He is said to have fallen at the siege of Meaux, and his death, on 8 Dec. 1421, certainly coincided with the bombardment of the town.

Buried: Spofforth, Yorkshire, England

Married (2nd): Christiana (Moubray) de Emeldon
This marriage occured before 24 February 1333(4) when Christiana is named the wife of William de Plumpton in a settlemnt of lands she held in dower (Calendar of the Patent Rolls Edward III 1334-1338 pp98-9)
((Christiana see CCR 1333-1337 p. 319; Close Rolls 1364-68 and Fine Rolls 1356-1368 p296, 300-1)

Plumpton Correspondence footnote to page xxii (ed. Thomas Stapleton, 1839)
the writer of the same notice [Controversy between Sir Richard Scrope and Sir Robert Grosvenor in the Court of Chivalry, royal 8vo, 1832. By Sir N. Harris Nicolas, K. H. vol. I. p. 270] thinks it most probable that Sir Robert was the issue of his father’s first marriage with Alice Byaufiz; but, letting alone the proof to be derived from his age at the time of the controversy, it is also certain that the manor of Brakenthwaite, with the lands which were of the inheritance of Alice, reverted, agreeably to the limitation in the fine noticed in the text, to the posterity of Thomas, son of Peter de Midleton, which could only be in case of failure of issue of Alice. (Plumpton Evidences.)

Children: Occupation: Knight, Sheriff and Escheator for Yorkshire, and Member of Parliament.
William was returned as knight of the shire for Yorkshire to the parliament of September 1331. In 1346 William is recorded as being in "the retinue of Henry de Percy and about to go in his company to the march of Scotland for the defence thereof." (Calendar of the Fine Rolls Edward III 1337-1347 p493). He was sheriff of Yorkshire and keeper of the castle at York from 22 October 1350 until 17 October 1351, and escheator for Yorkshire from 22 October 1350 until 1352. We find a number of orders given to William in his role as escheator in the Calendar of the Close Rolls Edward III 1349-1354. the Calendar of the Fine Rolls Edward III 1347-1356 and the Calendar of Inquisitions Miscellaneous 22-51 Edward III.

Notes:
William's seal, on documents from 1315 and 1325, is described as "a round shield with four fusils in fess" (Yorkshire deeds vol 4 in Yorkshire Archæological Society Record Series vol 65 p28). The first reference I have found to William as a knight is when he witnessed a grant on 6 February 1328 (Calendar of the Close Rolls Edward III 1327-1350 p361).

The Controversy between Sir Richard Scrope and Sir Robert Grosvenor vol 2 pp310-1 (N. Harris Nicholas, 1832)
    DEPONENTS IN FAVOUR OF SIR RICHARD SCROPE.
  SIR ROBERT PLUMPTON. The ancient family of which this knight was the representative had been seated at Plumpton in Yorkshire for many generations. His father Sir William Plumpton was twice married: first to Alicia daughter and heiress of Sir Henry Beaufitz; and secondly to Christiana Monasby, or Mowbray,1 widow of Richard de Emeldon;2 but pedigrees differ as to which of these women was the Deponent’s mother, though it is most probable that he was the issue of the first marriage.3

Of the marriage with Ros there was issue Robert de Plumpton, who married Joan, daughter of Sir John Mauleverer, kt. but died before consummation in his father’s lifetime; and Sir William de Plumpton, who had succeeded to the property before Monday next after the feast of St. Martin in Winter, 18 Edw.

II. 1325-6, upon Sir William de Plumpton and Alice his wife, and the heirs of their bodies, remainder to Thomas son of Peter de Midleton, and the heirs of his body, remainder to Marmaduke de Plumpton, and the heirs of his body, remainder to Adam son of Peter de Midleton, and his heirs for ever.q Sir William de Plumpton had to his second wife Christiana,r widow of Richard de Emildon, mayor of Newcastle in the reigns of Edw. I. Edw. II. and Edw. III. in the seventh year of which last reign he died.s She had re-married before 18 May, 12 Edw. III. 1338, being the Monday next before the feast of the Ascension of our Lord, for a settlement was then made of the manor of Grassington in Craven, to hold to Sir William de Plumpton and Christiana his wife, and the heirs of Sir William, by Henry de Spofford, chaplain, as feoffee in trust.t The same Sir William de Plumpton was the founder of a chantry, at the altar of the Holy Trinity, behind the high altar of the collegiate church of Ripon. The act of endowment is dated at Ripon, on Wednesday the feast of the Conversion of St. Paul, 20 Edw. III. 1345, and was sealed with the seals of Henry de Plumpton, the chaplain first appointed thereto, and of Sir William de Plumpton; which latter bore the impression of a shield and on it five fusils, with the name written in the circumference.u He died 36 Edw. III. 1362, towards the close of the year, as appears by the account of the feodary of the honour of Pontefract of that date, wherein is set down xxvs. as the relief of Robert de Plumpton, knight, for the fourth part of one knight’s fee in Idell, after the decease of William de Plumpton, knight, his father.x

54. WILLIAM DE PLUMPTON.  Sept. 1331.
  William de Plumpton was the s. and h. of Robt de Plumpton and his wife Lucy, dau. of Sir Wm de Roos. He mar., before 14 Apr. 1322, Alice, dau. of Sir Hen. Beaufiz by Cecily his wife. In 1324 he succeeded to his father’s estates, and was a kt in Sept. 1325.2 After the death of Alice he remar., before 24 Feb. 1334, Christina, wid. of Rich, de Emeldon of Newcastle.3 Wm was alive on 29 Mar. 1361/2, but d. towards the end of the yr.4 His s. Robt who succeeded was grandfather of the Robt de Plumpton who rep. the co. in the pari, of 1411 and 1416.5
  After Plumpton’s marriage with Alice Beaufiz, on 14 Apr. 1322, her father settled on them the man. of Nesfield, in Wharfedale,6 and the man. of Brackenthwaite with lands and tenements in Plumpton, Follifoot, Little Ribston, Kearby, Grewelthorpe and Kirkby Malzeard came to them after his death, most of these being settled on Wm and Alice with special entail in 1325.7 Plumpton alienated lands in Kirkby Malzeard, Grewelthorpe and South Stainley8 to found chantries in Ripon minster.9 He also held the mans. of Steeton, in Airedale, Grassington, and lands in Goldsborough.10 On the death of Hen. de Percy, whose retainer he was,11 it was found that he held of him lands in Ribston, Cowthorpe, Plumpton, Stockton, Steeton, Eastburn, and elsewhere.12 He acquired a small amount of land in Studley Roger in 1361.13
  Plumpton was retd as kt of sh. to the parl. of Sept. 1331,14 but played little part in affairs until Nov. 1344 when he was added to the comm. of the peace for the W.R.15 Two yrs later he was appd with John de Sigston to collect in the N.R. the aid of forty shillings from every k.f., but on 20 Jan. 1346/7, being about to go in the retinue of Hen. de Percy to the Scottish march, he was released from his office.1 On 8 Feb. 1349/50, he was appd on a comm. of o.t. and about this time he complained of the breaking of his close at Goldsborough and the carrying off of his goods.2 He was appd on 10 Apr. 1350 one of the colltrs of the fifteenth and tenth in the W.R., but was discharged within a month.3 Plumpton was shf of York and esch. in. the co. from Oct. 1350 until a yr later.4 On 6 Jul. 1351, he and others were entrusted with the task of arresting and taking to York cas. the murderers of John de Eland and his s., a band of desperate persons who had added to their offences by assaulting the js. appd to try them.5 About this time John de Mowbray accused him of hunting in his free chase at Kirkby Malzeard and Blanche de Mowbray charged him with breaking her closes and houses at Gribthorpe, Thirsk, Thornton (in Harthill wap.) and Newsholme, nr Howden, taking away livestock and assaulting her servants. In 1354 John again complained of his taking deer at Kirkby Malzeard and Burton-in-Lonsdale.6
  Meanwhile, on 20 May 1352, Plumpton had been appd on a comm, of o.t.7 He was constituted a j. of labourers for Claro, Ewcross, Sykrack, and Staincliff waps, on 10 Feb. 1354; for Barkston Ash, the Ainsty and Claro in Jul. 1354 and May 1355; and for the W.R. in Dec. foll.8 He was named in two more comms. of o.t. in 13569 and then his official career came to an end. On 24 Jun. 1358 he obtained exemp. for life from being required to serve on juries or to act as mayor, shf, esch., cor or other minister of the Kg against his will,10 and beyond a solitary comm, of o.t. in 136111 he did not receive further appt.

Plumpton Correspondence page xxiii - page xxvi (ed. Thomas Stapleton, 1839)
   In the reign of Henry the Fourth, Sir William Plumpton, the eldest son of Sir Robert Plumpton, suffered death upon a scaffold for the part he took in the insurrection stirred up by his uncle Richard, Archbishop of York, whose sister, Isabella Scrope his father had married. In the history of this commotion in Polydore Vergil, he is represented as the chief actor, a statement which subsequent historians have not thought deserving of credit; I, however, venture to introduce his account into these Memoirs, because that writer’s value as an historian appears to me to be sowewhat underrated, many of his details being evidently founded upon authentic documents, which have not survived the lapse of time, or which he may have wilfully destroyed, a practice imputed to this foreigner.
  “While Henry is thus attentive to his domestic concerns, William Plumpton, a brave and daring knight, formerly of the household of King Richard, along with some of the family of Thomas Mowbray, marshal, whom we have shown above to have died in exile at Venice, first excites the commons of Yorkshire and Durham to revolt, and then collects together a great number of armed men; and he conducts his proceedings with less circumspection than the nature of such an enterprise required, because his soul is mainly bent upon revenge. With him the Northumbrians also take part; and, last of all, the Scots; but these, as will be mentioned below, were not present at the outbreak. The King, meanwhile, informed of the design of the conspirators, for the sake of avoiding instant peril, took up arms, and, without a moment’s delay, marched directly to York; and such was his dispatch, that he had arrived there before the movers of the revolt had any certain intelligence of his coming. William Plumpton is instantly taken, and with him some of his associates; among whom was Richard Scrupp, Archbishop of York, who, although his name was in the highest repute for sanctity and virtue, nevertheless, accusers were not wanting to make it suspected that treason attached to him likewise, inasmuch as he sought thus to avenge the death of William, his brother, treasurer of Richard, whom Henry had put to death at Bristol, as I have shown in a former book. Whereupon Henry, having summoned a council of his nobles at York, he ordained an inquiry to be had, concerning the conspiracy. At this meeting all unanimously pronounce sentence of death against Plumpton, but as to the others, their judgment was more lenient. However, he having undergone capital punishment in the manner customary of old, the rest likewise are put to death, either by the axe or the gibbet.”a
  The historian here falls into the common error of making Archbishop Scrope brother of the Earl of Wiltshire and thus betrays the aim of his narrative, as meant to extenuate the rebellion of the Archbishop as much as possible. This he does by imputing to him a motive of natural affection which could not exist, and by supposing him to play quite a secondary part, while he shifts the chief blame upon Sir William Plumpton; whom also, as far as existing evidence goes, he falsely represents to have been of the household of King Richard. The verses formerly on the tomb of this unfortunate knight in Spofforth church tell a simpler tale:
    Miles eram dudum, Plompton Will’mus vocitatus,
    Præsulis atque nepos le Scropplis, hic tumulatus.
    Mortis causa sui, michi causa fuit moriendi,
    Mors capitis quippe nostrum male pressit utrumque.
    Anno milleno quater et C. sic quoque quinto,
    Penticostes me lux crastina sumpsit ab orbe.b
  In the year 1405 the morrow of Pentecost fell on the eighth of June, the feast of St. William of York, which is the day mentioned by Hall as that of their decollation, “on the Monday in Whitson weke.” This chronicler erroneously puts “Sir Robart” for Sir William Plumpton, and is exceeding angry with the writers and story-tellers who spread abroad that miracles were wrought at the time of the execution of Archbishop Scrope, as to the King’s being striken with leprosy, and the like. He doubtless here alludes to the History of the Martyrdom of Richard Scrope, Archbishop of York, by Clement Maidstone, where it is related, upon the authority of George Plumpton, an ecclesiastic of whom we shall speak largely in the sequel, who was an eye-witness, that on the day of the said decollation, 8th of June, great leprous pustules broke out over the said King’s face and hands, and were as prominent as the nipples of the breasts.c The vision of the son may, however, be believed to have been distorted by the recollection of his father’s execution, and by the wish, so natural to mortals, of seeing Heaven avenge our wrongs: the legendary should, at all events, have taken the precaution to look out for a more disinterested witness, before he gave publicity to the tale.
  No act of attainder followed upon the execution of the rebels, and Sir Robert Plumpton, the father, obtained for himself a general pardon for all treasons and felonies;

  We have yet another account of the Archbishop’s reasons for demanding a reform set forward in the year after his death by the Earl of Northumberland, Sir Edmund Mortimer, and Lord Bardolph, for the information of their sympathizers, in the hope of stirring them again into revolt . They tell us that the Archbishop advised the King to repent and make satisfaction for his perjury in forcing Richard to resign his crown, but the advice (if really given) must have sounded strange in the mouth of one of the leading Commissioners who had received the crown from the captive King, and sealed the renunciation deed with the sanction of the Parliament. They tell us that the Archbishop now wished the crown to be restored to the right line, that lords should be tried by their peers, that taxes should be lightened, and that “certain wise men” should be appointed to take the place of greedy foreigners and hungry adventurers who would say anything to please the King, that sheriffs should be elected without the pressure of official interference , and that all estates should be free to speak their mind in Parliament. But in all this there is nothing new. Every adherent of the Percies at Shrewsbury was pledged to the same vague cry. It only proves that the Archbishop’s sympathies were now set against the King, that he threw himself into the conflict this time without disguise, and, as he said, “rode with the crowd.”
  When the articles appeared on the church doors, he donned his jack and went amongst the citizens of York crozier in hand, cheering, exhorting, and threatening. All who should fall in the sacred cause were assured of pardon for their sins and full remission. The minster pulpit echoed to the battle call. The Archbishop preached for the articles. Let the people insist that Parliaments should be free, that the members should be the elected representatives of the boroughs and counties, not the nominees of the King. Let those who knew the law be summoned “in their wisdom,” and let the Parliament be held in London, where abuses could be probed, not in some petty upland town, where the court could carry all its own way. Copies of the articles were sent also to the curates of the neighbouring villages, with orders to have them preached there likewise. Seeing the gathering without and the enthusiasm within the walls, the waverers were silenced and all York declared for the articles. The Archbishop, the Earl Marshal, and Sir William Plumpton (a nephew of the Archbishop’s), who had long been busy fomenting disturbance, put themselves at the head of a motley following of priests, monks, peasants, and townsmen, and set out to try their fortunes in the field.
  The “priestly rout” was furnished with such arms as they could get. Before them went a banner with the five sacred wounds displayed, and as they moved along their numbers swelled to 8,000 fighting-men “or thereabouts.” No time was to be lost. It was known that the Earl of Westmoreland had escaped the snare, and that he and Prince John were moving a strong force down from the Scottish border. A band of 7,000 or 8,000 rebels was collecting from Cleveland, Northallerton, and Topcliffe, to join the Archbishop’s force from York. Their leaders were all North Yorkshire knights, viz.:—Sir Ralph Hastings, of Slingsby and Allerston, near Pickering; Sir John Fauconberg, a member of a house that had great estates in Cleveland and Holderness, and heir to the castle of Skelton, as descended from the historic Yorkshire family of Bruce; Sir John Fitzrandolph, from Spennithorne, near Middleham, in Wensleydale; and Sir John Colvil, of Daletown, in Ryedale, and Arncliffe, near Stokesley, where a fragment of the new Charthouse of Mount Grace of Ingleby still shows the Archbishop’s arms worked in stone over the entrance to one of the cells in a corner of the cloisters. Robert Takell, Prior of Warter, near Pocklington, joined the muster with his canons and his tenants, as did Geoffrey Wymeswold, Prior of the Gilbertines at Old Malton . Takell is called in the register of his priory a “good and religious man,” but no mention is made of his fighting instincts. He was one of those who ran away and managed to survive the disaster, together with quite a flock of chaplains, clerks, curates, and friars, including Simon Wenslaw, parson of Colne, in the hills of Lancashire.
  The Cleveland force marched southward towards York, supporting themselves as best they might by robbing, wrecking, and slaughtering wherever their requisitions were refused. But haste again made waste. They had been forced prematurely into the field and had to halt at Topcliffe, on the Swale, to await the expected arrival of the Earl of Northumberland. Here they were attacked and dispersed, and the four knights fell prisoners into the hands of the royal troops.
  The Earl of Westmoreland had marched southward with the utmost speed to check the head of the rising, and by a rapid move had wedged himself between the two rebel forces, ready to strike at both before they could combine. He had with him Prince John, who was placed under his charge, and he was supported by an old and experienced negociator, Sir Ralph Ewere, of Witton, and the Archbishop’s fiery nephew, Sir Henry Fitzhugh, Lord of Ravenswath, near Richmond, a “very noble and very valiant knight,” whose great after-career showed him “so much endowed with sense, nurture, and courtesy, that he deserved the right to be claimed father of nobility and gentleness.” With them was also Sir Robert Umfraville, famed for his “sapience and very gentleness, his liberal heart and knightly governance,” though these great qualities did not save them from committing an act of the basest treachery when the chance fell in their way.
  The Earl of Westmoreland had planted his force on the sloping ground called Shipton Moor, about six miles to the north-west of York, on the fringe of the wooded and boggy plain known as the Royal Forest of Galtres. The Earl had long been officially responsible for the charge of the forest, which stretched northwards between the Ouse and the Foss, from the gates of York to Aldborough and Sheriff Hutton, where he had lately strengthened the fortifications of Bertram de Bulmer’s castle. The greater part of the wood had been felled, the colliers were busy stubbing up the stovens and carting them away for “coals,” the wolves and wild boars had become extinct, and the swampy wilderness that had long been the terror of travellers, was already transformed into rich grass land, or assarted to tilth and earing.
  The Earl had already sent a detachment to deal with the gathering at Topcliffe when he saw the Archbishop’s force advancing from the walls of York. He had the best of the ground but the worst of the numbers, and both sides seemed to shrink from beginning the fray. For three days the two bands confronted each other with banners spread. At length, on May 29th, the Earl sent to ask the reason for such show of war. The Archbishop replied that he was working, not for war, but for general peace, but that he could not approach the King in safety unless he came munited with men. He handed to the messenger a scroll of the articles and bade him show them to those who sent him.
  It seemed as though for the moment the fortunes of the dynasty were in the hands of the Earl of Westmoreland. A borderer, a Nevil, a kinsman of the Percies, lord in his own right of the great castles of Brancepeth, Raby, Penrith, Sheriff Hutton, and Middleham, and charged for the time being with the custody of Richmond, Roxburgh, and Carlisle, he might have lowered his standard and taken his troops over, carrying the young Prince a captive into the rebel camp. But family hatreds were the King’s salvation, and Ralph Nevil again stood firm to the side which the Percies abandoned. To the messenger he professed to be much struck with the Archbishop’s “pious and sacred” proposal, and urged a conference that he might learn more of the suggested plans of reform. The leaders should meet on open ground in front of their forces with a few attendants only at their side. The Earl Marshal, who had a special grudge against the Earl of Westmoreland, was suspicious, but the Archbishop would not mistrust his old friend and neighbour. Base treachery could not be hinted against such worthy and righteous knights; and so the Earl Marshal’s young scruples were overcome, the Archbishop put on his iron corslet, and the two advanced to the selected ground attended by Sir William Plumpton, Sir William Lamplugh, a Cumberland knight, and Sir Robert Pershay or Percy, of Ryton, near Pickering. The Earl of Westmoreland was awaiting them with Prince John and Sir Ralph Ewere. On each side there was as equal number of armed attendants, while the armies stood off at a distance and “waited the end.”
  The little company met and bowed and ordered the articles to be read. They were piously and justly framed, said the Earl of Westmoreland , and no sane man could help but support them. For himself, he would do his utmost to secure their carrying out, and induce the King to accept them if he could. Then followed hand-shaking, congratulations, and chat. “But look,” said the Earl, “now that our task is done and you have talked us over, let us drink together in the open that all may see that we are friendly and agreed.” The cups were set and the little drinking-party began. Sir Henry Fitzhugh was sent over to the rebel army announcing that the leaders were in agreement, and that all cause for hostile feeling was removed. It was the Archbishop’s wish that they should not await his return, as he would sup with the Earl of Westmoreland that night. Knowing that the leaders had fraternized together, though they could not actually see them owing to a slight rise in the intervening ground, and feeling already the inconvenience of a three nights’ absence from their homes, many of the York men slipped away in groups to resume their ordinary occupations. Many also of those who had been brought up from the Midlands and the Eastern counties by the Earl Marshal had joined the expedition with much reluctance; few only were left to watch over the safety of their leaders; “as the Bishop’s men voided the other party increased”; and so, when the rank and file began to mix, these few were speedily disarmed, and the Archbishop, the Earl Marshal, and the three knights submitted helplessly to be detained, under a promise of future indemnity after conference with the King.
  The many improbabilities in the accounts given in contemporary writers were first insisted upon by Guthrie. He preferred the view which lays stress upon the fact, that the Archbishop and his party surrendered of their own accord, being convinced that further resistance was hopeless. This is quite consistent with the other portion of the account given above, if we remember that the Archbishop was probably now, for the first time, made aware of the capture of his friends at Topcliffe, and was offered his life if he would submit. Nevertheless, the story of the treachery is too well authenticated to be dismissed altogether. In the official statement in which Pope Gregory XII. attempted three years afterwards to excuse King Henry for his share in the matter, it was represented that a battle took place in which the Archbishop was captured, though Henry, not being there, did not know what was going on.
  The dogs being thus withdrawn, the silly sheep who remained were pursued and worried; some of the rustics were caught and heavily beaten, the rest “scaled and fled.” Grey Friars had not learnt wisdom from their taste of the fruits of sedition three years before. Many of them were again with the rebels. Eighteen were caught by the irreverent royalists, who stripped off their gowns, took down their “infirmities,” and so let them run away home. The Archbishop, the Earl Marshal, and the knights, were then hurried off under guard to Pontefract castle, to await the daily-expected arrival of the King; while the Earl of Westmoreland and Prince John returned to Durham with their forces, in readiness for the attack of the Earl of Northumberland. 
  We have seen that the King had already decided that no glory was to be gained by hanging about the bleak borders of Wales. He had scented the battle in the North, his old spirit was awake, and he moved straight from Worcester by forced marches from day to day (de jour en autre). By May 28th, 1405, he had reached Derby, whence he posted orders to the members of the council in London to come instantly north to Pontefract, each with his best array according to his station, for advice and help. From May 30th to June 1st he halted at Nottingham. It was found that in consequence of the failure of the rebellion at York, a general scramble was going forward to secure a share of confiscated property in Yorkshire, Lincoln, and Nottinghamshire. Measures were therefore taken to prevent looting, and orders were sent (May 31st) to the Sheriff at York to seize all the property of the Archbishop and the other rebels into his hands, in the King’s name. Sir Ralph Rocheford, Sheriff of Lincolnshire, and Sir Richard Stanhope, Sheriff of Nottingham and Derby, had accompanied the King from Hereford and Worcester, and did good service now in their respective counties.
  On June 2nd, 1405, the King was at Doncaster, and the next day, June 3rd, he arrived at Pontefract. The Archbishop was standing alone on one of the castle towers, watching for his approach. As the head of the company drew near, he took his crozier and went down to the court-yard by the entrance gate. Having no friend with him he beckoned to a priest in the court and called on him to be his crozer, and the two advanced to the gateway ready for the arrival of the King. Sir Thomas Beaufort, who was standing by, told him that a traitor was unworthy to carry the “crouch,” and bade him in the King’s name to give it up, snatching it at the same time from the hands of the priest. The Archbishop turned on him and wrenched it violently back, crying out with warmth that the King had no right to take away what the Pope alone could bestow. Then followed a stiff tussle in which the Archbishop got some ugly handling, and the crozier was roughly wrested from his grasp.
  When the King drew near, the Archbishop threw himself upon the ground and begged for pardon, but Henry ordered him back and refused all interviews till he should be able to consult with his council. His rage was at a white heat. He stormed against the citizens of York, and vowed that he would wipe them off the face of the earth, if they resisted further. He sent forward Sir John Stanley and Sir Roger Leche of Chatsworth with commissions to seize upon York and occupy it under martial law. On the 4th of June, a strong commission was appointed, of whom Sir Thomas Beaufort, Richard Lord Grey of Codnor, Chief Justice Gascoigne, Sir John Stanley, Sir William Fulthorpe, Richard Norton, John Conyers, and Gilbert Elvet were the chief, to try all persons concerned in the rebellion. On the same day, orders were issued to Prince John and the Earl of Westmoreland to seize all property belonging to the Earl of Northumberland, Sir William Stanley, the elder brother of Sir John Stanley, being sent with a small force to the Isle of Man to take possession of it in the King’s name. Prince John was likewise authorized to pardon where he should see fit, reserving all forfeitures to be dealt with subsequently by the King. Having forwarded these arrangements Henry left Pontefract with all his forces, and on the 6th of June, 1405, he planted his foot in the Archbishop’s manor at Bishopthorpe, on the Ouse, three miles to the south of York. Here, as the Constable and Marshal had their hands full in the extreme North, and might possibly be cut off from communication with head-quarters, he appointed the Earl of Arundel and Sir Thomas Beaufort as their deputies, to fulfil all requisite duties for the temporary emergency, and having thus made his preparations he stood ready to deal his blows at the heart and life of the conspiracy.
  Already a panic had seized upon the citizens of York. They dressed themselves in rags and streamed out from the gates ungirt and barefoot, some holding out their swords, others with ropes in their hands, or halters round their necks, louting and flinging themselves upon the ground with sobs and cries, to beg the King’s pardon and grace. He railed upon them and told them to get back to their homes, and that no man was to say anything was his own, till he had made up his mind what he meant to do; and he sent to Pontefract for the Archbishop and the Earl Marshal that the dupes whom they had pushed into rebellion might see them meet their doom. On the day on which he arrived at Bishopthorpe, a fresh commission was issued containing the same leading names as those of June 4th, with the exception of Richard Norton, whose place was taken by Henry Retford. It may be that differences had already begun to develop themselves among the first Commissioners, and the names of the Earls of Arundel and Warwick, and the Lords Willoughby, Grey of Ruthin, Roos, and Darcy were now added to the list.
  Very early in the morning of Monday, June 8th, 1405, before the King had left his bed, he was surprised by the arrival of an unexpected visitor. Archbishop Arundel had hastened to the North on hearing the news of the great capture. On the 7th of June, when well on his way, tidings reached him that Archbishop Scrope and the Earl Marshal were to die the next day. He was still two days journey from York, and it was Whitsunday. Nevertheless he crowded his devotions into one private mass, took with him a notary, and posted right on. Snatching short moments to throw themselves on the straw in the wayside stables, as they halted to bait their jaded horses, and riding on through the night, they reached Bishopthorpe at sunrise on Monday morning, and the Archbishop, all travel-stained and besmuttered from the dusty road, made his way into the King’s sleeping room. He warned him earnestly of the danger he would run, the sin he would commit, and the punishment he would incur, if he laid a hand on an Archbishop’s life. Fearing the effect that his passionate pleading might have upon the King, some of those present in the room remonstrated that they would not answer for the consequences if the rebel Archbishop were allowed to live, and they hinted significantly that there were other enemies of the King still in the field,  and not so far off, who would give him trouble yet, if he set so little value on the support of his loyal counsellors and friends. Archbishop Arundel then made his last appeal to the King. As his spiritual father and the second person in the realm, he claimed the right to be consulted. “If he has done such wrong, leave him to the judgment of the Pope, or at least of the Parliament, but at your peril smirch not your hands with his blood.”
  The King was in a dilemma. He could not gainsay the Archbishop, and he dared not flinch from his resolve in the presence of his courtiers. He was now more self-possessed. He soothed the Archbishop, told him that his efforts quite had his sympathy, but that he could not openly grant his request because of its possible effect upon his supporters. He urged him to lie down for awhile and rest, and then, after hearing mass, they would talk it over together at breakfast, and he promised that nothing should be done without a distinct order from himself. Arundel was satisfied, he turned to his notary to write down the King’s engagement, and betook himself to rest.
  Pressed by the party of action the King sent straightway for Chief Justice Gascoigne, and called upon him to pass the death sentence on the Archbishop and his associates as traitors. As to Sir William Plumpton there would be no hesitation. He was known to have excited the men of Durham and Yorkshire to insurrection. He had been a personal friend of King Richard. His doom was sealed and he would be sentenced to die. But beyond this the Chief Justice refused to go, alleging that neither the King nor any of his subjects could legally pass sentence upon a Bishop of the Church.
  The story of this famous refusal comes to us on the authority of an eye-witness, Sir Thomas Cumberworth, of Somerby, near Brigg, in the Lincolnshire Wolds, whose nephew, Sir Robert Constable, of Flamborough, afterwards married Judge Gascoigne’s daughter Agnes. It proves not only the courage and independence of the Judge, but also his prudence and his intimate knowledge of the King’s character. He knew that he was ruled by impulse, which must in due course burn itself out, when remorse would seize upon him and find vent upon his instruments in this wanton and impolitic outrage. The Judge’s legal scruples were undoubtedly well grounded. Seventeen years before, in 1388, an Archbishop of York, Alexander Nevil, uncle to the Earl of Westmoreland, had got himself into similar trouble by meddling in a political intrigue, and had been duly declared to be guilty of treason. But though his companions were condemned to be drawn and hanged, yet the Parliament hesitated to take his life, alleging that “such a case had never been seen in the realm touching the person of an Archbishop or Bishop.” They contented themselves with securing his deprivation by the Pope, seizing his property and sentencing him to perpetual banishment. Nine years later (in 1397), Archbishop Arundel was found guilty of high treason, but, though his brother who was implicated with him was beheaded forthwith, yet even the victorious party in Parliament did not call for the death-penalty on “so high a person as the Father of his realm.” They only asked that he should be put “in safe keeping in honourable manner,” and he was accordingly sentenced to forfeiture and banishment during the King’s pleasure, which meant no more than a visit to Rome, where the Pope conferred upon him even larger revenues from English benefices than he had held when he was in the King’s favour, by means of which he could plot handsomely to return and recover more than all his former influence in the retinue of a rebel and usurper. If then King Henry now commanded sterner treatment for his rebel Archbishop, it is no wonder that the legal mind of the Chief Justice recoiled. Besides, Judge Gascoigne was bound in terms of personal intimacy with many of the leaders and sympathizers in the rebellion. Rather therefore than act with the extreme advisers of the court, he rose and left the hall.
  His place was taken by Sir William Fulthorpe, of Tunstall, in Durham, a son of that judge who had been knocked down and kicked by King Richard, at Nottingham, in 1387, for daring to ask the contents of a document before putting his seal to it. Fulthorpe is usually represented as a mere soldier, put up to carry out the King’s brutal behests when Gascoigne’s finer conscience refused to violate the law. But Fulthorpe’s father had been a judge, his own son afterwards became a judge, and that he himself had some repute for legal knowledge is shown by his appointment as legal representative of the Constable of England. In 1408, he presided in a court of chivalry and heard the complicated pleadings in the dispute between Sir Edward Hastings and Lord Grey of Ruthin, delivering the judgment in 1410, when he was described as “one of the sages of the council of the court”; and in 1411, we find him arguing intricate points of law with the judges in matters referring to the jurisdiction of the Constable’s Court. Being now called to preside where Gascoigne had refused, he showed no scruple on the score of illegality or sacrilege. He was supported by the Earl of Arundel and Sir Thomas Beaufort (the temporary Vice-Constable and Vice-Marshal) and Sir Ralph Ewere, who represented the forward party on the Commission.
  While the King and Archbishop Arundel were breakfasting together, Archbishop Scrope, the Earl Marshal, and Sir William Plumpton were brought before the Commissioners in the great hall at Bishopthorpe, and stood bareheaded to listen to their doom. There was no trial or inquiry. Fulthorpe at once, in the name of his colleagues, pronounced them to be traitors, taken red-handed, and by the King’s order sentenced them to the block. The Archbishop showed no sign of penitence. He protested that he had meant no harm against the realm or the person of the King, and turning to the by-standers he called on them repeatedly to pray that God would not take vengeance for his death on King Henry and his house. The three were then ordered off to York for instant execution.
  The Archbishop prepared with fitting dignity to take a last farewell of the world. He asked to be allowed to ride to his death dressed in his linen rochet and carrying his crozier in his hand; but this was refused, and he was brought out in a scarlet chymer with a violet hood drooped over his shoulders. A collier’s sorry mare, not worth a mail, was fetched; the Archbishop thanked them for the mount and rode bare-back, with a halter for bridle, amidst a dense throng, out on the road to York.
  As the three passed along, the young Earl Marshal showed signs of giving way, but the Archbishop maintained his composure and cheered his fainter fellows with the thought that the death-pain would be but for a moment, and that they would die in the cause of justice. Catching sight of an old acquaintance on the road, John Malvern, the King’s physician and mire, he rallied him gaily, saying: “I shall need no physic from you now, Master John.” “Perhaps not for the body,” said the leech, who was a “professor of truth” as well as a master of physic, “but you will need it for your soul.” “Come sir," said the Archbishop, “and watch me die, and if you see aught against the truth, I bow to your correction.”
  They halted at the south-western corner of the walls, where the high road enters the city, close to the river bank by the Skeldergate postern, and passed into a field belonging to the nuns of Clementhorpe, where the young barley was waving in the freshness of early summer. The day was the anniversary of the death of St. William, when the little fertour with his relics was carried in procession through the city. Crowds from all parts, both mounted and afoot, thronged into the field and the crop was soon pounded and trampled beneath their feet. As the procession drew near, the owner of the crop stepped out and begged that his rigs might be spared and the block be placed elsewhere. There was no scaffold to erect and the man’s request might have been granted. The Archbishop did his best, and asked that he might be taken out for execution on the highroad close by. But the officers had strict orders that would brook no sort of delay. They hurried him forward saying that a traitor could not choose his place of death. The block was on the ground, and a convict, Thomas Alman, of Poppleton, who had served fifteen years imprisonment in York gaol, had been brought out to do the work of blood.
  The Earl Marshal and Sir William Plumpton died first, while the Archbishop stood by and prayed. Speaking to those near enough to hear, he said: “I die for the laws and the good government of England.” He then removed his hood and coif, and laid them on the ground. Turning to the headsman he bade him deal five blows at his neck in memory of the five sacred wounds, kissed him three times and kneeled for a moment in prayer. Then folding his arms across his breast he stretched out his neck and “took his death with full good will.” A faint smile still played on the features when his head fell at the fifth stroke, and the body rolled over on its right side. He died, “as some think, a worthy and a lovely martyrdom.”
... Sir William Plumpton’s head was set up on the Bar at Micklegate, until the 17th of August, 1405. It was then given up to his wife Alice and buried in the church at Spofforth, where his epitaph might still be read 200 years afterwards. His name was piously linked with that of the Archbishop, his uncle, by succeeding generations of Scropes when providing for their memories in later days.

Constitutional History of England vol 3 pp50-2 (William Stubbs, 1903)
It was said that on the 28th of February Glendower, Mortimer and Northumberland had signed an agreement for a division of England and Wales between the three. The lord Bardolf, who had opposed the king strongly in the recent councils, had joined Northumberland, and Sir William Clifford had associated himself with them. Unfortunately for himself and all concerned, the archbishop of York, Richard le Scrope, placed himself on the same side. These leaders drew up and circulated a formal indictment against the king, whom they described as Henry of Derby. Ten articles were published by the archbishop; Henry was a usurper and a traitor to king and church; he was a perjurer who on a false plea had raised the nation against Richard; he had promised the abolition of tenths and fifteenths and of the customs on wine and wool; he had made a false claim to the crown; he had connived at Richard’s murder; he had illegally destroyed both clerks and prelates; and without due trial had procured the deaths of the rebel earls, of Clarendon and of Hotspur; he had confirmed statutes directed against the pope and the universities; he had caused the destruction and misery of the country: the tenth article was a protest that these charges were not intended to give offence to the estates of the realm. Another document stated the demands of the insurgents in a less precise form. They demanded a free parliament, to be held at London, to which the knights of the shire should be duly elected, without the arbitrary exclusion which the king had attempted in the parliament of Coventry. Before this assembly four chief points were to be laid: the reform of government, including the relief of church and nation from the unjust burdens under which both were groaning; the regulation of proceedings against delinquent lords, which had been a fruitful cause of oppression; the relief of the third estate, gentlemen, merchants, and commons, to be achieved by restricting the prodigality of the crown; and the rigorous prosecution of war against public enemies, especially against the Welsh. These demands, which were circulated in several different forms, certainly touched all the weak points of Henry’s administration, and, although it must ever remain a problem whether the rising was not the result of desperation on the part of Northumberland and Mowbray rather than of the hope of reform conceived by Scrope, their proposals took a form which recommended itself to all men who had a grievance. As soon as it was known that the lords were in arms Henry hastened to the north, and having reached Derby on the 28th of May summoned his forces to meet at Pomfret. The contest was quickly decided. The earl of Westmoreland, John of Lancaster, and Thomas Beaufort, at the head of the king’s forces, encountered the rebels on Shipton moor and offered a parley. The archbishop there met the earl of Westmoreland, who promised to lay before the king the articles demanded . lords, 1405. The friendly attitude of the leaders misled the insurgent forces; they dispersed, leaving Scrope and Mowbray at the mercy of their enemies, and they were immediately arrested. In spite of the earnest pleading of archbishop Arundel and the refusal of the chief-justice, Sir William Gascoigne, to sanction the proceedings, the king allowed his better judgment to be overruled by the violence of his followers. On the advice of Thomas Beaufort and the earl of Arundel, he determined to sacrifice his prisoners: he obtained the assistance of Sir William Fulthorpe, who acted as president of the tribunal of justices assigned, and on the 8th of June the archbishop and the earl-marshal were beheaded. That done, the king followed the earl of Northumberland and Bardolf to the north. They fled to Scotland, and Henry, having seized the castles of the Percies, returned to the task of defence against the Welsh.

Of this son, when in his twelfth year, the marriage was contracted for on the part of Sir Bryan de Stapilton, of Carlton, com. Ebor. knight, in behalf of his daughter Elizabeth, an infant of the same tender years. The agreement bears date 20 Jan. 3 Hen. V. 1415-16; thereby Sir Bryan accords, that a sum of CCCLX marks be paid to Sir Robert Plumpton for the marriage, he agreeing to settle an estate of xx marks yearly in the vill of Kinalton on his son William and Elizabeth, and their issue. He was further to engage to make a feoffment to Sir Richard Redmayn, knight, John de Moute, esq. Robert Brame and Roger Spofford, chaplains, of the manor of Steton, to secure a rent-charge of XL marks yearly, in case that if the said William and Elizabeth were legally ousted of the estate in Kynalton by Sir Robert or his heirs, or the heirs of Dame Alice his late wife, then the feoffees to convey the same to William and Elizabeth. Within a month after the death of his mother, Dame Alice de Plumpton, Sir Robert was to add x marks to the yearly rent out of Kynalton, except in case Dame Margaret Rempston or Thomas Foljambei pre-deceased his mother, or that she herself happened to die during the minority of her grandson William. There were beside covenants for re-payment of the principal, in case of either of the parties dying without issue, or of divorce before consummation, as well as of a further sum of L marks for the costs of their maintenance. It was also stipulated that Sir Robert de Plompton should not make any feoffment or estate to the disinherison of the said William, his son, of the land which he held, either by descent, or curtesy after the death of Dame Alice his late wife; save only he might give rent-charges of xx marks each to his two younger sons Godfrey and Robert, with right of mutual accretion in case of either of them being promoted to a benefice, or advantaged by marriage, and of survivo ship in case of death. Also, he might jointure any future wife he might take to himself, so as the jointure did not exceed C marks. Sir Bryan de Stapilton and Dame Agnes his wife were to have the governance of the said William and Elizabeth during their minority, receiving for their sustenance the rent of xx marks out of Kynalton; but in case Sir Bryan should happen to die, and his widow take a second husband, then Sir Robert was to have the governance of the betrothed parties.k

Plumpton Correspondence page lxxiii - page lxxix (ed. Thomas Stapleton, 1839)
  The private life of Sir William Plumpton from the time of his wife’s death appears to have caused no small scandal in his neighbourhood. Besides being avowedly the parent of two bastard sons, named William and Robert, his offspring by his second wife, Joan Wintringham, by reason of the concealment of their marriage, was long looked upon by the publick in the same light. His intentions in favour of this son by the second venter have been already adverted to; and the covenants cited from the contract made with Mr. Sotehill, show him to have been then preparing the way for his production, at some future period, as the legitimate heir and acknowledged successor to his fortunes. This last act was apparently precipitated by the censures of the Church; for it having reached the ears of the Official of the Civil Court at York, by clamorous report of both sexes, that Sir William Plumpton kept one Joan Wintringham in his house at Plumpton, and had begot on her divers offspring in amplexibus fornicariis, to the great peril of his soul and grievous scandal of all the faithful, that officer issued a summons for his appearance before him. Whereupon Sir William Plumpton attended in the chapel or oratory of St. Thomas the Martyr, in the Cathedral Church of York, on Tuesday the 26th day of January 1467-8; and the question being then and there put to him, he publickly declared that he had kept the said Joan in his house, not as his concubine, but as his true and lawful wife, for many years past; and that they had issue between them an only child, begotten of her body after marriage had and solemnized in the parish church of Knaresburgh; but in as much as no banns had been published, and the marriage was a clandestine one, he expressed himself ready on that acconnt now to submit himself to the censure of the Church, and to make satisfaction. Being required to produce witnesses of the truth of what he alleged, evidence was given as below, on Saturday the 13th of February following.
  “Sir Robert Littester, chaplain, of the age of forty years, domestic servant to Sir William Plumpton, kt. deposed, that about eleven years ago there was a great muster of Englishmen to oppose the Scots, to which muster the said deponent happened to ride, together with the said Sir William Plumpton, his master, as far as Skipton-upon-Swale; and between the vills of Balderby-in-les-Broome and Skipton, the said Sir William called the said deponent to him, saying, Robert, do you now return home: and I beg of you to listen well to all I am going to say, and above all to what concerns my weal and honour in my household. And because the event of war is dubious, and the solempnization of marriage between me and Joan Wintringham, my wife, has not yet been openly and publickly notified, I hereby make known to you that the said Joan is my true married wife and I her true married husband. And thus I wish and desire you, as you love me, if I happen to die in battle, to testify for the future, wherever it may be necessary.”
... In the meanwhile, the proceedings of the Ecclesiastical Courts for the canonical recognition of Sir William Plumpton’s second marriage were continued, and this further evidence adduced in that behalf on the sixth of July, 1472.
  “Richard Clerk, parish clerk of Knaresburgh, Yorkshire, of the age of fifty years and more, deposed, that he had known Sir William Plompton for fifty years and more, and Joan Wintringham from the time of her birth—that on a certain friday, which exactly he does not remember, between the feasts of Easter and Pentecost, about twenty-one years ago, in the parish church of Knaresburgh, was solempnized a marriage between the said Sir William and Joan—that at that time he was, as now, parish clerk of Knaresburgh, and was present on this occasion—that the preceding night John Brown, then perpetual vicar of Knaresburgh, sent word to the deponent that Sir William Plumpton intended to marry Joan Wintringham on the morrow, she then sojourning with Alice Wintringham her mother in Knaresburgh, and therefore he bade him wait on him very early the next morning and open the doors of the church for him, and so he did—and very early in the morning of the said Friday came the said Sir William and Joan to the parish church of Knaresburgh—and, they standing at the door of the chancel of the said church within the said church, the aforesaid John Brown came from the high altar in his vestments and solempnized marriage between them in the presence of the deponent, the said Sir William taking the said Joan with his right hand and repeating after the vicar, Here I take the Jhennett to my wedded wife to hold and to have, att bed and att bord, for farer or lather, for better for warse, in sicknesse and in hele, to dede us depart, and thereto I plight the my trouth, and the said Joan making like response incessantly to the said Sir William—that the vicar, having concluded the ceremony in the usual form, said the mass of the Holy Trinity in a low voice in the hearing of the deponent—that there were present at the marriage the said vicar, the contracting parties, Alice Wintringham mother of the bride, Thomas Knaresburgh of Knaresburgh, Richard Askham of Kirkdighton, Richard Exilby of Knaresburgh, and John Croft, his fellow witness, and no more—and immediately after the marriage the said Sir William earnestly entreated those present to keep the matter secret, untill he chose to have it made known—and further that Sir William was clad in a garment of green checkery, and Joan in one of a red colour.”
  “John Croft of the age of forty years, domestic servant of Sir William Plumpton in his chamber, deposed to the same effect as his fellow-witness, adding that Joan Wintringham had on a grey hood—that the marriage was celebrated before sun-rise—and that he had kept silence untill within the last five or six years.”i
  Upon the hearing of this evidence, Doctor William Poteman, the official of the court of York, on the 13th of the same month, certified that Sir William Plumpton, kt. and Joan Wintringham, were legally married;j and from that time Robert Plumpton, the son by this marriage, was taught to consider himself as the heir apparent of his father’s house, and the future owner of his property. Legal obstacles were, however, likely to interpose to prevent the intended eviction of the heirs general, and it became advisable to take fresh steps to effectuate the now avowed purpose of the interested parties. Conveyances were accordingly executed of the several estates of Sir William Plumpton to feoffees, viz. Richard Andrewes, dean of York, William Eure, clerk, Sir John Norton, kt., Ranulph Pygot, John Arthington of Arthington, Godfrey Grene, and Richard Knaresburgh; of the manor of Plumpton, together with the advowson of the chantry of the Holy Trinity in the cathedral church of Ripon, 12 Oct.;k of Garsington in Craven 13 Oct.;l of Idill, with the advowson of a chantry at the altar of St. Nicholas in the church of St. Martin in Mekilgate, 14 Oct.;m of Steton, same day;n of Kynalton 30 Oct.;o of the manors of Chaddesden, Derley, Stainton, Edinsor, Pillesley, Hassop, Wormehill, Chelmerton, with the advowson of a chantry at the altar of St. Cross in the church of Baukewell, and of another in the chapel of St. Margaret, of Elton, and of all hereditaments in the same places, and in Hurdlow, Flagfeld, Queston, Cumbes, Martinside, Betfeld, Tidswall, Castleton, Wardlow, Rowland, Baukewell, Calton Lees, Beley, Broughton, Twyford, Spounden, Newbold, and Lokhaw in the county of Derby, Crakemarsh, and Combrig in the county of Stafford, Mansfeld, Woodhouse, Hykling, Owthrop, and Colston in the county of Nottingham, with the advowson of a chantry at the altar of St. Mary in the church of Mansfeld Woodhous, 2nd Nov. and of Okbrook, with the hereditaments there and in Burrosasshe, 6th Nov. 15 Edw. IV. 1475.p The said feoffees resettled the same upon Sir William Plumpton for term of his life, with remainder in tail to Robert Plumpton, junior, son of Sir William and Joan his wife, and the heirs of his body, remainder over to Sir William’s right heirs; save that as to the manor of Plumpton, of a close with buildings on it called Roughferlington, and of the manors of Garsington and Steton, Com. Ebor., and of Kynalton, Com. Notts., the first limitation was to Sir William Plumpton and Joan his wife for their lives, and in the manor of Okbrook, after the life estate of Sir William Plumpton, certain parcels were to be enjoyed by his bastard sons, William Plumpton, junior, and Robert Plumpton, senior, for the term of their natural lives.q

  e See Memoirs for what relates to the clandestine marriage of Sir William Plumpton and Joan Wintringham, his second wife. This lady was living 19 Oct. 12 Henry VII. 1496, when she passed some copyhold lands in the court at Knaresborough to her son, before Thomas Coghill, the bailiff of the liberty, (Chartul. No. 785,) but was dead in the following year, 1497, when by reason that Sir Robert Plumpton had given for the repose of her soul the twentieth part of a ducat to the re-building of the greater hospital at St. Jago de Compostella, her name was to be associated with all those prayed for by that community, with a share in all spiritual indulgences according to the tenor of the bulls of Popes Innocent VIII. and Alexander VI. (Chartul. No. 788.) The informalities attending her marriage required atonement, and in the Chartulary are copied numerous certificates of the Indulgences which her husband and herself had obtained in return for alms bestowed on different religious communities both at home and abroad. Dodsworth, among his Church Notes, has the following memorandum: “Knaresborowgh Church, 28 Sept. 1622. There is a quire in the south side called Plumpton’s quyer, which belonged to a house in the town called Wintringham Hall.” (Dodsw. MSS. in Bibl. Bodl. CLX. fol. 186.) The same antiquary has also preserved to us this description of a painted north window then remaining in the same church. “A man in ar. kneeling, on his breast b. 5 fusells in fesse or, (Plumpton); his wiefe behind him, on her breast the former coat paled with ar. a (inescocheon) ent. an orle of martletts. g. (Wintringham); under, Orate pro a’i’a. . . . . . . . .Plumpton et etiam pro anno a’i’a d’n’i Will’mi Plumpton qui istam . . . . . . . . anno . . . . . Qu’rly. b. 5 fusells in fesse or, and sa. a [bend] ent. 6 [escalops] or, (Foljambe): paled with it, an [inescocheon] ent. 9 martletts in orle. g.” Dodsworth appears to have either overlooked the escallops on the fusells, the distinguishing charge in the coat of Plumpton, or they had become imperceptible from lapse of time.  

Dictionary of National Biography vol 15 p1321 (ed. Sidney Lee, 1909)
  After the first wife’s death, or perhaps before it, Sir William had two bastard sons, Robert and William. Great scandal was caused at a later date by his relations with Joan, daughter of Thomas Winteringham of Winteringham Hall, Knaresborough. In consequence, Sir William was summoned before the ecclesiastical court of York, where he appeared in 1467-1468, and declared that he had been privately married to the lady in 1451. After some delay the court decided in 1472 that this was true, and from that time Robert, the offspring of this marriage, was regarded as heir. To make all sure, his father made him a gift of his personal property.

Children: Occupation:
William set out for the French wars about 1427 and was knighted before 1430, when he returned. He probably went to France again very shortly, as he is mentioned as one of the captains in the retinue of the Duke of Bedford in 1435. He was seneschal and master-forester of the honour and forest, and constable of the castle of Knaresborough from about 1439 to 1461, and in connection with this office he had serious trouble in 1441, when a fierce and sanguinary quarrel broke out between the tenants of the forest and the servants of Archbishop John Kemp as to payment of toll at fairs. On 20 Feb. 1441-2 he was appointed by the Earl of Northumberland seneschal of all his manors in Yorkshire. In 1448 he was sheriff for Yorkshire, and in 1452 for Nottinghamshire and Derbyshire.

Notes:
William is recorded as Robert's son and heir in Robert's IPM on 13 October 1432.

The Plumpton Correspondence (ed. Thomas Stapleton, 1839) contains a large number of letters mainly written to Sir William Plumpton, the earliest being from Henry VI on 13 March 1460, calling him to battle. The book also contains an extensive biography of Sir William on page xliii - page lxii. I have excerpted parts of the biography and one of the letters, from King Henry VI ordering him into battle against Edward then Earl of March, later Edward IV.

Plumpton Correspondence page xliii - page lxxxvi (ed. Thomas Stapleton, 1839)
  On the seventh of October, the feast of St. Marcus, Pope, 6 Hen. IV. 1404, Sir Robert Plumpton had born to him a son and heir,h afterward Sir William Plumpton, knt. and the same with whose correspondence the series of letters commence.
... The issue of Sir Robert Plumpton and Alice Foljambe were three sons: 1. William, in his eighteenth year at the time of his father’s death; ... The wardship of William de Plumpton till he attained his age devolved of right upon the Earl of Northumberland as lord of the Percy fee of which the chief manor in Plumpton was held.
... Having now attained his majority, “Willelmus Plumpton, de comitatu Ebor. armiger,” procured letters of general attorney, tested at Westminster 27 Jan. 5 Hen. VI. 1426-7, and shortly after set out for the wars in France;b from which service he had returned but just before 28 Sept. 9 Hen. VI. 1430, being then a knight.c
... In 14 Hen. VI. 1435-6, Sir William Plompton, knt. was a Commissioner with Sir William Gascoigne, Sir Robert Waterton, knts. William Ingelby, Thomas Clarell, Guy Fairfax, John Thwaites, John Gascoigne, and Robert Malleverer, to array men-at-arms, hoblers, and archers, in the Westrithing of Yorkshire, and to send them to the sea coast to repel the threatened invasion; also to make muster of the said troops, and to place signals called Bekyns in accustomed and convenient places to warn the people of the approach of the enemy.f
... Sir William Plumpton was Senescal and Master Forester of the Honour and Forest, and Constable of the Castle, of Knaresborough from about the 17th year of Henry VI. 1439, to the close of that reign ... During his tenure of office, a dispute as to the right of the tenants of the forest of Knaresborough to pay toll at fairs, was made the preliminary to a serious affray with the officers, tenants, and servants of John Kemp, Cardinal and Archbishop of York, on the 5th of May, 19 Hen. VI. 1441, in which lives were lost. ... To these several counts Sir William Plumpton made answer in denial or explanation; but as no further proceedings appear to have been taken in the matter it may be presumed that a compromise was effected, and that the right of the Archbishop to the “denier of toll” was sealed with the blood of his tenants and servants.
... Dame Elizabeth, wife of Sir William Plumpton, is named with her husband in a certificate of admission to the fraternity of the guild of St. Christopher at York, signed by John Skinner, master and guardian, and dated 31 Aug. 17 Hen. VI. 1439;a but she was dead before the marriage of her eldest son Robert, (born Thursday, 8 Mar. 9 Hen. VI. 1430-1,)b to a daughter of Thomas, Lord de Clifford and Westmorland, was contracted for; ... Robert Plumpton, esq. died on Monday, the feast of St. Margaret the Virgin, 20 July 1450,e in the nineteenth year of his age, without having consummated his marriage with Elizabeth Clifford, who three years later was married to William, brother of Robert, and only surviving son of Sir William Plumpton by his wife Elizabeth Stapilton. ... At the time of the marriage of his son, Sir William Plumpton was himself clandestinely married to Joan Wintringham, sister to the wife of his brother Godfrey, and who had given birth to a son; from which cause he was now seeking to effect a settlement of his lands on his heirs male, so as to give a preference to this son by the second venter over any female issue of his eldest son, should he die leaving only such surviving. ... by two several deeds of the same date, viz. 23 Aug. 31 Hen. VI. 1453, Sir Thomas Rempston, knight, (his uncle in half-blood, and sole surviving feoffee under the deed made by his father 24 Sept. 8 Hen. V. 1420, and under his own feoffment of the 18th April 17 Hen. VI. 1439,) entailed all the estate of which he stood enfeoffed in the counties of York, Derby, Nottingham, and Stafford, together with the reversion of what was held by Dame Margaret Rempston for her life, upon Sir William Plumpton and his heirs male, with remainder to Godfrey Plumpton, his brother, and his heirs male.h
  But to return to Sir William Plumpton’s public career. By deed of the 20th Feb. 19 Hen. VI. 1441-2, Henry Earl of Northumberland and Lord of the Honour of Cockermouth, appointed Sir William Plompton, knight, to be Seneschall of all his manors and lordships in the county of York for the term of his life, with an annual fee of 10li;i to which, 1 Nov. 26 Hen. VI. 1447, was added for his good services a second 10li per annum, issuing out of the manor of Lethelay in com. Ebor.k In 1448 he was Sheriff of the county of York, and in 1452 of the counties of Nottingham and Derby. In 1456 Sir William Plumpton rode northward with the forces mustered by the Earl of Northumberland, for the purpose of making an incursion upon the Scottish borders;l and upon the breaking out of the wars of the Roses, he, as a matter of course, sided with his suzerain and master, the said Earl of Northumberland, and with him fought in support of the House of Lancaster.
...  After Edward had assumed the title of King, and during the time he was on his march into the North, to enter into conflict with the partisans of the dethroned monarch, these two mandates addressed by Henry VI. to Sir William Plompton, kt. followed in rapid succession. The first, “tested at York, 12 March, 39th of our reign,” contains an order for Sir Richard Tunstall, kt. Sir Thomas Tresham, kt. and Sir William Plompton, kt. to summon all liege men of the forest or demesne of Knaresburgh, to set out with them to meet the enemy;o the second, “geven under our signet, at our cyty of York, the thirteenth day of March,” straitly charges “our trusty and welbeloved knight, Sir William Plompton,” to repair to the royal presence with his array in all haste possible.p On the 29th of the same month, being Palm Sunday, Sir William Plumpton was present at the decisive battle of Towton, otherwise Saxton field; where William, his son and heir apparent, it seems, was slain, and he himself either made prisoner by the enemy on that day, or driven by the adverse fortune of his party shortly afterwards to throw himself on the mercy of Edward. On the 13th of May he came before Robert Danby, Chief Justice, in the city of York, and gave bond for the payment of £2000 before the feast of Pentecost next ensuing, whereupon the following writ was issued in his behalf.
  “Edward, by the grace of God, King of England and of France and Lord of Ireland, we will and straitly charge all our true liegemen and subgitts, that none of them upon paine of death, under any colour or occasion whatsoever it be, robbe nor spoile William Plompton of Plompton, in our County of York, knight, nor none of his servants, ne tenants, nor none of them; nor contrary to our lawes hurt, trouble, or vex them, or any of them, in anywise, in body or goods. Geven under our privy seale at our Citty of York, the xiiith day of Maie, the first yeare of our reigne.”r
  The term for redeeming of this bond having elapsed, on the 12th of July, 1461, Sir William Plumpton surrendered himself a prisoner at the Tower of London; and, having been sworn according to custom, was admitted by Sir William Bowischer [Bourchier,] kt. lieutenant of the Tower, to all the liberties and privileges of the place.s He obtained letters of general pardon, 5 Feb. 1 Edw. IV. 1461-2,t and was subsequently, 10 Sept. 2 Edw. IV. 1462, released from all claim by reason of his bond.u But notwithstanding Sir William Plumpton had afresh letters of pardon dated 30 Aug. 3 Edw. IV. 1463,x he was, it seems, restricted from returning home into the North; and was at one time in jeopardy of his life, by reason of the denunciation of one David Routh, son of late Thomas Routh, of Westminster, who laid these overt acts of treason to his charge:
  “First, Sir William Plompton, with other persons, within the place of Honslough, the second and third years of the reigne of our soveraigne and liege lord, had receyved, red, and understaud false, damnable, diffamatory, and slaunderous writing, traiterously by pen and other forged and ymagined against the honor and welfare of our said soveraigne, and the same sent to other suspicious persons to corage and comfort them by the same.
  “Also he hath received in the said place divers persons coming out of Scotland fro the Kings adversaries, and secretly cherished them, succored, forbored, and their secrets concealed.
  “Also he hath sent messengers into his countrey, which there receyved tidings of his brother men there out of Scotland, fro the Kings adversaries, by his brother assent and his.
  “Item. When any turble or enterprise was leke to fall hurt or scaythe to the Kings people, the said Sir William Plumpton, with oder suspected, rejoyced, and were glad in chere and countenance.”
  Upon these charges Sir William Plumpton was tried before the Earl of Worcester, Lord Tiptoft and of Powis, Great Constable of England, and a jury of twenty-four, at Hounslow, shortly before Christmas. Having been acquitted, he obtained a warrant from the Constable to be rid of all further molestation on that behalf, dated 20 Jan. 3 Edw. IV. 1463-4,y as also the following brief from the King.
  “Edward, by the grace of God, King of England and of France and lord of Ireland, To all maiors, sherifs, eschetors, baliffs, constables, and other our ministers whatsoever they be, and to all other our true liege people, greeting. We lett you witt, that our welbeloved William Plompton Kt. hath truly, sufficiently, and clearly declared himself of all manner matters that have been said and surmised against him, and so we hold him thereof for fully excused, and declared by these our present letters. And we take him, hold, and repute him as our true and faithfull leigman. Wherefore we will and charge you, all and every one of you as much as to him belongeth, that from henceforth ye, nor any of you, neither vex, moleste, greive, trouble, nor him nor any of his, in body nor in goods, otherwise then our lawes will; nor that ye give or shew unto him, or any of his, any ungodly language or countenance, but that ye take him and suffer him to abide and go att his pleasure and ease, there as him shall best like, as other our true leiges do; not breaking this our comaundement, as ye will eschew our great displeasure, and upon payne of punishment by our laws. Yeven under our signett att, &c.”z
  Being now reputed loyal, Sir William Plumpton was restored to his offices of Constable of the Castle, and Master Forester of the Forest of Knaresborough, and to the Stewardship of the Lordship of Spofford, of which he had had grants for life in the previous reign.
... on Sunday the 15th Oct. 1480, Sir William Plumpton died,t leaving issue by his second wife, Joan Wintringham, Robert, their only child.
... The Correspondence of Sir William Plumpton, any more than the facts elicited in the preceding memoir, presents his character in no very favourable light; fond of litigation, we find him ever letting matters proceed to extremities before taking up his obligations, and to gain time, availing himself of practices “not worshipful”—an adept in deceit, paying court to one mistress, though secretly married to another—fraudulent in his dealings, obtaining money for the marriage of his grand-daughters, when it must have been his fixed resolve to strip them of their inheritance—abusive of his authority, “suing every true man in the Forest,” and fearing not to shed blood in the assertion of pretended rights—immoral in his conduct, suffering an innocent wife to labour under slanderous report during years of silence—and time-serving in his loyalty, amassing wealth and coveting offices of trust under Princes of either House. Of the degree of eminence he raised himself to by these unworthy means, a strong proof may be found in the licence which he obtained from King Edward IV. to embattle his manor-place at Plumpton, and to enclose a park, there with liberty of warren and chase.f The edifice thus built is noticed by the antiquary Leland in his Itinerary, in these words: “From Gnarresborow over Nid river almost al by wood a mile to Pluntone wher is a park and a fair house of stone with 2 toures longging to the same.”g At the visitation of St George Norroy, in 1612, there was remaining in the Hall at Sir Edward Plumpton’s this shield, “quarterly, Plumpton and Foljambe, impaling Stapleton with the mullet,” the armorial bearings of this Sir William Plumpton and his first wife Elizabeth Stapleton. In the chapel were the coats, Plumpton impaling Clifford—Darell impaling Plumpton—Hamerton impaling Plumpton—and “Argent, a fess between three wolves’ heads erased Gules;” perhaps the arms of office of the Master Forester of Knaresborough Forest.h

Dictionary of National Biography vol 15 pp1320-1 (ed. Sidney Lee, 1909)
  PLUMPTON, SIR WILLIAM (1404-1480), soldier, born 7 Oct. 1404, was eldest son of Sir Robert Plumpton (1383-1421) of Plumpton, Yorkshire, by Alice, daughter of Sir Godfrey Foljambe of Hassop, Derbyshire. His family had been settled at Plumpton from the twelfth century, and held of the earls of Northumberland as overlords. Accordingly the Earl of Northumberland had his wardship till he was of age. About 1427 he set out for the French wars; he was knighted before 1430, when he returned. He probably went to France again very shortly, as he is mentioned as one of the captains in the retinue of the Duke of Bedford in 1435. He was seneschal and master-forester of the honour and forest, and constable of the castle of Knaresborough from about 1439 to 1461, and in connection with this office he had serious trouble in 1441, when a fierce and sanguinary quarrel broke out between the tenants of the forest and the servants of Archbishop John Kemp [q. v.] as to payment of toll at fairs. On 20 Feb. 1441-2 he was appointed by the Earl of Northumberland seneschal of all his manors in Yorkshire with a fee of 10l. for life; the fee was doubled for good service in 1447. In 1448 he was sheriff for Yorkshire, and in 1452 for Nottinghamshire and Derbyshire. He continued closely connected with the Percy family, and in 1456 joined the musters of the Earl of Northumberland for a raid into Scotland. This family connection drew him, like most of the northern gentlemen, to the Lancastrian side in the wars of the Roses. In 1460 he was a commissioner to inquire into the estates of the attainted Yorkists. In 1461 the series of letters addressed to Sir William Plumpton which forms part of the ‘Plumpton Correspondence’ begins. On 12 March 1460-1 King Henry wrote from York telling him to raise men from Knaresborough and come to him. The next day a second letter urged him to hasten. He joined the royal army and fought at Towton, where his son William was killed. Sir William either gave himself up or was taken prisoner, and decided to submit. He obtained a pardon from Edward IV on 5 Feb. 1461-2. For some time, however, he was not allowed to go into the north of England, and in 1463 was tried and acquitted on a charge of treason by a jury at Hounslow, Middlesex. He now recovered his offices of constable of the castle, and forester of the forest of Knaresborough; but, like most of the people of the north, he must have made some move in the Lancastrian interest in 1471, as he secured a general pardon for all offences committed up to 30 Sept. 1471, and at the same time lost his offices at Knaresborough.
  He died on 15 Oct 1480. He married, first, some time after 20 Jan. 1415-16, the date of the marriage covenant, Elizabeth, daughter of Sir Bryan Stapilton of Carlton, Yorkshire; she died before 1451. By her Sir William had seven daughters, all of whom married, and two sons, Robert and William; Robert died in 1450, being betrothed to Elizabeth, daughter of Thomas, lord Clifford; upon his death Elizabeth married his brother William; the latter was killed at Towton in 1461, leaving two daughters. After the first wife’s death, or perhaps before it, Sir William had two bastard sons, Robert and William. Great scandal was caused at a later date by his relations with Joan, daughter of Thomas Winteringham of Winteringham Hall, Knaresborough. In consequence, Sir William was summoned before the ecclesiastical court of York, where he appeared in 1467-1468, and declared that he had been privately married to the lady in 1451. After some delay the court decided in 1472 that this was true, and from that time Robert, the offspring of this marriage, was regarded as heir. To make all sure, his father made him a gift of his personal property.
  This SIR ROBERT PLUMPTON (1453-1523) was involved in various disputes with his father’s other heirs He was knighted by the Duke of Gloucester, near Berwick, 22 Aug. 1482, when following his master, the Earl of Northumberland, but he supported Henry VII after he had secured the crown, and went to meet the king on his northern progress in the first year of his reign. He was also present at the coronation of Queen Elizabeth on 25 Nov. 1487. That he was trusted by the king may be gathered from the lease granted to him on 5 May 1488 of mills at Knaresborough and Kilinghale, and he took an active part in repressing the outbreaks in Yorkshire of April 1489 and May 1492; Henry thanked him in a letter which is printed among the ‘Plumpton Correspondence.’ Despite this evidence of his loyalty, Empson fixed his claws in the Plumpton inheritance, and raked up the old claims of the heirs-general of Sir William Plumpton. In 1502 the verdict went against Sir Robert; but he appealed to the king who made him a knight of the body, and in 1503 he was protected from the results of the action. The dispute was not, however, finished; and when Henry VIII came to the throne, Sir Robert, who was penniless, was imprisoned in the counter. He was soon afterwards released and an arrangement made by which he was restored to his estate on an award. He died in the summer of 1523. He married, first, Agnes (d. 1504), daughter of Sir William Gascoigne of Gawthorp, Yorkshire; by her he had a large family, of whom William Plumpton was the eldest son. Sir Robert’s second wife was Isabel, daughter of Ralph, lord Neville, by whom he does not appear to have left any issue.
  The ‘Plumpton Correspondence.’ was preserved in a manuscript book of copies which passed into the hands of Christopher Towneley about 1650, and remained among the Towneley MSS.; it consisted of letters written during the time of Sir William Plumpton and later members of his family down to 1551. It was edited for the Camden Society by Thomas Stapleton [q. v.] in 1838-9 (2 vols,); the letters illustrated by the editor by extracts from a manuscript in the same collection, the ‘Coucher Book’ of Sir Edward Plumpton.

Plumpton Correspondence page lxxxvi - page lxxxviii (ed. Thomas Stapleton, 1839)
  Some time before his death, 1 May, 18 Edw. IV. 1478, Sir William Plumpton had made an absolute disposition of all his personal effects, moveable and immoveable, in favour of his son,i so as to preclude the necessity for any will; consequently the only memorial respecting him remaining in the ecclesiastical court at York is a commission from the official, dated 10 Jan. 20 Edw. IV. 1480-1, for John Quixley, chaplain, and Richard Plumpton, to collect the debts and make the inventory of the effects of the intestate, which they were to retain in their custody.k In regard to the landed estate, it was matter of urgent necessity that the title of Robert Plumpton, the son, should be admitted before the Escheator, and that the office found upon the inquisitio post mortem of his father should be returned in that sense to the Court of Chancery. The mode of ensuring this result we learn from the following document:
  “This indenture, made the last day of November, the yeare of the reigne of King Edward iiiith the xxth, Betwene William Gascoigne, knight, on that one party, and Edmund Parpoint Exchetor for our Lord King, in the shyres of Nottingham and Derby on that other party, Witnesseth, that the said William Gascoigne, knight, and the said Exchetor be agreed in manner and forme that followeth; that is to say, that the said Exchetor shall indevor him to do that belongeth him in his said office, as well in the shire of Nottingham as in the shire of Darby aforesaid, to find an office after the decease of William Plompton, knight, now dead, and to make his precept to the Sherife of the said shires, and to write to the saide Sherife to have such men impannelled as abovesaid William Gascoigne shall name. And that the said Exchetor shall cause to his power both the offices, as well in the one shire as in the other, to be found betwixt this and the feast of Nativity of our lord God next comeinge, according to such evidence as shal be shewed there by the counsell of the said William Gascoigne, knight, of all such mannors, lands, tenementes, rents, revercions, and services, with other appurtenances, of which the said William Plompton, knight, now dead, was seised of in fe, or otherwise, in the said shires, in his life, or any other to his use. For which the said William Gascoigne, knight, shall pay or cause to be paid to the said Edmund Parpoint iiiili for his office so found, retorned and put into the Chauncery of our said sovereigne Lord the King, according to the right and title of evidence above rehersed, and xxs for his reward; which putting in shalbe att the charge & cost of the said William Gascoigne, knight. And also the said William Gascoigne, knt. shall save the saide Edmund Parpoint, Exchetor, harmles for the said office so found and retorned. In witnes whereof either party interchangeably to this Indenture hath setto their sealls. Written the yeare and day abovesaid.”l
  Inquisitions were taken according to this agreement before the said Escheator at Derby on the 18th of December, and at Lenton in Nottinghamshire on the 20th of the same month; and in both the feoffment to Master Richard Andrews, Dean of the cathedral church of York and his co-trustees, with the subsequent limitation to Sir William Plumpton for life, remainder to Robert Plumpton, jun. his son, and the heirs of his body, and then to his right heirs, is set forth. In the one, the finding is that de tali statu inde obiit seisitus, remanere inde in forma predicta;m but the estate in Nottinghamshire having been reconveyed to Sir William Plumpton and Joan his wife conjointly, the finding is that she survived him et se tenuit intus per jus accrescendi.n The jury upon the inquest in Yorkshire made a like return according to the tenor of the feoffment produced before them, the same I have adverted to above. This office was taken by William Netilton, Escheator, at Wedirby, on Friday before the feast of St. Martin in winter, 10th Nov. 20 Edw. IV. 1480;o and in it, as also in the others, are the usual findings of the day of the death of the deceased, and the names and ages of the heirs-at-law, the daughters of William Plompton, esq. son and heir of the said Sir William Plompton, knight, viz. Margret, wife of John Roucliffe, of the age of twenty years and more, and, Elizabeth, wife of John Sothill, of the age of nineteen years and more: save that in the later inquisitions, Margret is returned of the age of twenty-one years and more.
