Hamon began his career with the expectations of a younger son. His influential father seems originally to have intended that he become a mercer, apprenticing him in the late 1440s to Henry Frowyk I*; but better opportunities soon presented themselves, and the young Hamon found a place in the royal household, where his cousin Henry Vavasour was already in service. He was a yeoman of the Crown by 1450, when the burgesses of Kingston-upon-Hull paid him a mark for delivering to them a royal writ of privy seal, and he was soon after promoted to the Chamber.
The young Hamon’s prospects were greatly improved by the death of his elder brother early in 1452, which left him heir apparent to a large estate in the city of Lincoln and its environs. On his marriage, which probably took place soon after he had acquired this status, his father settled upon him and his wife in joint tail-general his outlying manor of Salmonby near Horncastle and that of Ownby-by-Spital, much nearer the main Sutton lands, valued together at just over £10 p.a. in 1467.
Hamon’s father died in the autumn of 1461, and in the following February our MP took the precaution of suing out a general pardon.
Early in 1467 Sutton’s high status in society was marked by his appointment, like his father before him, to the Lindsey bench.
