Wilcombe is first recorded in 1333, presumably while still a young child, when a settlement was made of land in Chiltington, Sussex, on his father Robert for life, with remainder to him. From 1344 he also had a reversionary interest in property at Piddinghoe held by his brother, Thomas. Having attained his majority, in 1356 he acquired a moiety of East Chiltington manor, to which in the following year he added land at Pyecombe and Clayton given to him and his wife, Mary, by his father.
As a young man, Wilcombe was retained by Richard, earl of Arundel (d.1376). Thus he came to be named among the adherents of the earl and the prior of the Dominican friary at Chichester when the earl was summoned to appear personally in the papal court at Avignon in October 1364, following allegations of injuries caused by them to the bishop of Chichester, only for the personal citation to be revoked and the earl ordered to appear by proxy. That he was close to other members of the earl’s family, too, is clear from his nomination in 1375, together with Richard Fitzalan, the future earl, as executor of the will of his aunt Katherine, widow of Lord Hussey and of Sir Andrew Peverel†.
The precise date of Wilcombe’s death is not known, although it happened after 1392 and before May 1399, when his widow died.
