It is possible that the Welsbournes originated from one of the two villages of Wellesbourne in Warwickshire. They were certainly of obscure origin, in spite of their later claims of descent from Richard de Montfort alias Welsbourne, a fictitious son of Simon de Montfort. Richard was supposed to have settled at Hughenden, immediately to the north of Wycombe, and in Henry VIII’s reign those of the Welsbournes residing in that parish went to the length of erecting a fake tomb for their imaginary ancestor in the church there.
The MP is frequently difficult to identify; partly because of the lack of a genuine Welsbourne pedigree and partly because he shared a name with other members of his family. He had probably reached adulthood by September 1404, when the Crown, reacting to reports of lawless behaviour by William atte Halle and his adherents, commissioned Sir Hugh Holes and other Buckinghamshire gentry to investigate. It was said that John Wyke alias Welsbourne, Jude Wyke and others had ambushed and assaulted William Saunderton at West Wycombe, and that they and many other members of atte Halle’s ‘affinity’ had risen against Saunderton and his friends, with the intention of killing them and burning their houses.
There is no information for any trade or profession Welsbourne may have pursued. Evidently one of the leading men of Wycombe, as his time as its mayor and his election to Parliament indicate, he was a tenant of both Bassetsbury, the duchy of Lancaster manor which encompassed most of the borough, and the Hospitallers’ manor of Temple Wycombe.
In September 1443 Welsbourne and his wife conveyed a close in Walton (near Aylesbury) to John Baldwyn the elder and others, although to what purpose is not known.
By the mid 1430s the MP was known as ‘John Welsbourne senior’, to distinguish him from his son, who sat for Wycombe in the Parliaments of 1447 and February 1449 and joined the King’s household. In 1443 the MP was in dispute with two of his debtors (both husbandmen from Buckinghamshire) in the court of common pleas, but it is unclear whether it was he or his younger namesake who sued Ralph Paselewe of Wycombe and his wife for trespass in the same court in the following year.
