Nothing is known about this MP’s background, although it may be the case that he was related to John Gatcombe, a Wiltshire merchant recorded as a creditor at the staple at Salisbury in the early years of the fifteenth century.
A continued association with Seymour doubtless lay behind Gatcombe’s second election to Parliament, in 1432, when he sat for Marlborough. There, Seymour (like his maternal grandfather Sturmy before him) was a person of consequence, and it may not have been mere coincidence that he, as sheriff of Wiltshire, was the man responsible for sending the electoral returns to Chancery. Gatcombe’s third election, for Cricklade in 1435, saw him accompanying Seymour, one of the shire knights, to the Commons.
