Few details of William Jane’s career prior to his election to the Bury Parliament of 1447 have come to light, but it is probable that he was a kinsman of Stephen Jane* who was returned to the same assembly as a Member for Launceston. If so, it is possible that he, like Stephen, was connected with the Courtenays of Boconnoc, who had recently succeeded to a portion of the estates of the ancient Carminowe family and who, in (Sir) Hugh Courtenay*, supplied one of Cornwall’s knights of the shire on that occasion. Certainly, ties of both lordship and kinship played a part in the Cornish elections of 1447: William Jane’s parliamentary colleague, John Nanskelly II*, was not only a relative of his, but also the son of Courtenay’s fellow shire knight, John Nanskelly I*. Moreover, both the Nanskellys and Janes owned property in the vicinity of Truro, in the case of the latter on the Roseland peninsula.
The extent of William’s own landholdings (none of them demonstrably in the Truro area) is unclear, but in 1451 his property was assessed at no more than 40s. p.a. for taxation purposes.
Within a few years of these events, Jane took up more permanent residence at Launceston, and rose to such prominence in the town as to be elected one of the stewards on two occasions in the 1470s, and eventually to serve as mayor. Indeed, the townsmen came to rely on his experience to such an extent that he was one of two men charged with standing surety for the borough’s loyalty in the aftermath of the Cornish rising of 1497.
