William Gosse continued a long-standing family tradition of service in the Commons. His grandfather and namesake had represented Bridgwater in Henry V’s first Parliament, and his father had found seats in two other south-western boroughs during Henry VI’s minority. The younger William was first returned during his father’s lifetime, in January 1449 (when he shared a lump payment of 40s. in lieu of his customary wages with his parliamentary colleague, John Mauncell*), one of at least three occasions when Richard Gosse attended the election of the knights of the shire in the county court at Ilchester and set his seal to the sheriff’s indenture.
Certainly, Gosse did something to earn the gratitude of the newly-crowned Edward IV, for in December 1461 he shared with George Middleton* (who had sat alongside him in the Parliament of 1460 as a burgess for Dorchester) and William Seward a grant of the Somerset manor of Huntspill, forfeited by the recently executed earl of Wiltshire.
Few other details of Gosse’s career have been discovered. In 1471 and 1472 he twice found sureties for the appearance of one James Neweham before the King’s council, and in a separate, probably unconnected episode in July of the latter year, the details of which remain obscure, the mayor of Bridgwater and other commissioners were ordered to arrest him and his putative brother John Gosse and to bring them before the council for their part.
