Thomas Peyton (1418–1484) of Isleham, Cambridgeshire, was twice Sheriff of Cambridgeshire and Huntingdonshire, in 1443 and 1453. He rebuilt the church of St Andrew's in Isleham, in the chancel of which survives his monumental brass. He is depicted in a 1485 stained glass window in Long Melford Church, Suffolk, where he displays on his surcoat the Peyton arms: Sable, a cross engrailed or a mullet in the first quarter argent.
