William's birth date is uncertain. William's father Robert died in 1325/6. William's first wife, Alice Beaufitz, was born about 1297, and was 28 years old in 1325 when Robert died. William and Alice married before 14 Apr 1322. Assuming William and Alice were about the same age, he was also born about 1297.
William was knighted before 19 September 1328, as evidenced by his being listed as Sir William de Plumpton, among the witnesses to a charter of Sir Henry Percy on that date.
On 24 August 1330 a Commission of Oyer and Terminer was appointed to investigate a complaint by John de Mowbray that William, and numerous others, had driven away livestock and had taken game from his property.
William was a Knight of the Shire for Yorkshire in 1331. He was a retainer of the Percy family, and there are records of him going to the borders with Scotland, in the 1340's, to serve with Henry de Percy.
In 1345 William gave lands to St Wilfrid's Church, Ripon, Yorkshire for divine service for the benefit of the souls, himself, and members of his family.
William was Sheriff of Yorkshire, and Escheator of the county in 1350-1351. While he was sheriff, there was a complaint by John and Blanche de Mowbray, that William and others had assaulted their men and servants at Kirkby Malzeard, Yorkshire, and had driven away livestock and taken deer. In the 1350s he served on various commissions of Oyer and Terminer. In 1351 William and others were commissioned to arrest the murderers of John de Eland. In 1354 he was appointed one of the Justices to enforce the Statute of Laborers in parts of Yorkshire.
Most of William's lands were in Yorkshire, but there are also records of his holding property at Brenkley, near Newcastle-upon-Tyne.
In March 1362 William made a second gift of lands to St Wilfrid's Church, Ripon, Yorkshire, to provide for a daily service for the souls of the faithful departed. William died late that year.
Marriages & Children
Sir William married twice. His first wife was Alice Beaufitz. They married before 14 April 1322, when his father settled lands on him and his wife Alice. They had no issue.
His second wife was Christiana Mowbray, who had been married twice before: she was widow of John Scot of Benwell, Northumberland, and Richard de Emeldon, who died in the Battle of Halidon Hill in 1333. They married before 24 February 1334. The Close Rolls have an entry, dated 30 June 1334, relating to her dower. William and Christiana had at least two children:
Alice, wife of Sir Richard de Sherburne and then of Sir John le Boteler,
Durham Visitation evidence suggests there may have been a third daughter, Margaret, not listed in Dugdale’s Visitation or Douglas Richardson's works: see the Research Notes. She is shown here as an uncertain daughter.
Christiana died not long after William, in December 1363.
Mother of Robert and Alice
Dugdale’s Visitation gives William de Plumpton’s first wife Alice Beaufitz as mother of his children Robert and Alice. William married his second wife Christiana by 30 June 1334. Robert was said to be age 45 in 1385, so he cannot have been a son of Alice.
Margaret is named in the Visitations of Durham as a daughter of a Sir William Plumpton, for whom no further identification is given, and as wife of Christopher Selby, but with no dates. The dates of the William of this profile could fit. There is nothing in the Visitations to identify William further, and these Visitations are not always accurate. Douglas Richardson states that William de Plumpton and Christiana had one son and one daughter, Robert and Alice, for both of whom there is good sourcing. Dugdale’s Visitation of Yorkshire lists just Robert and Alice. No other source for a daughter Margaret has yet been found. Margaret, therefore, is shown as an uncertain daughter of William and Christiana.
Questionable Children Martha and Emma
Another child has previously been attached to William and Christiana: Martha. The only source for her profile is Burke's Commoners, 1835, which says that Brian Palmes married a daughter of a William Plumpton Esq. of Plumpton, with no dates given, and does not even give a first name for her. In the absence of stronger evidence, Martha has been detached.
Charles Davies Sherborn's A History of the Family Sherborn raises the possibility of a further daughter, Emma: he states that Robert Sherburne, brother of the Richard Sherburne who married William and Christiana's daughter Alice, is said to have married Emma, daughter of Sir William de Plumpton, in 1356.

William (Plumpton) de Plumpton has also been identified as being in a trail between Gateway Ancestor Peter Worden and Surety Baron Robert de Roos, which is currently under development prior to review and approval by the Magna Carta Project. See the proposed trail on the profile for Peter's mother, Isabel (Worthington) Worden, in the Magna Carta Project section. See Base Camp for more information about Magna Carta trails. ~ Douglass-990 14:09, 16 February 2018 (EST)
I have now completed the main work I intend on this profile, subject to checking for typos etc (if you spot any, please correct them). After asking a question in G2G, I have detached a daughter for whom there is next-to-no evidence, adding a research note, and made another daughter uncertain. I've replaced a very long quote from a web article with factual info referenced to sources cited in that article and to other sources. I have removed some duplication of info. Please feel free to improve the profile further.
I have started work on this profile, and will be aiming to replace the very extensive quotation from Douglas Hickling with factual material drawn from it and other sources. I have asked a question in G2G about whether there is enough evidence to justify retaining Martha and Margaret as daughters of him and Christiana de Mowbray.
Hello PMs! Wanted to let you know that I'll be working on this profile as part of Peter Worden's Magna Carta Trail on behalf of the Magna Carta Project. Please don't hesitate to reach out if you have any questions.
