Although difficult to distinguish from contemporary namesakes, Martin certainly resided in the borough for which he sat in three Parliaments. A tenant of Bassetsbury, the duchy of Lancaster manor encompassing most of Wycombe, he obtained a grant of copyhold lands at Oakridge in May 1437. The grant was for life, although four years later he returned to the manor court to surrender the lands, so that William Frere might have them on like terms. In the same month, the King, in his capacity as duke of Lancaster, granted Martin the duchy’s warren and woods at Wycombe. This was in return for his ‘past and future good service’, although it is unclear if this phrase referred to an office held locally or to a more significant attachment to the Crown.
Probably still alive in the mid 1440s, when a John Martin was acting as a feoffee for two Buckinghamshire gentlemen, Edmund Hampden* and Thomas Cheyne,
