Considerably more may be added to the earlier biography.
It is likely that this MP was a relation of Gilbert Hamme of Withyham in north-east Sussex, a lawyer who regularly appeared as a mainpernor in the Exchequer for members of the local gentry in the early fifteenth century. If so, he is to be identified with the John Hamme who himself held land at Withyham subsequently.
The fact that Hamme was later returned for the Surrey borough of Bletchingley may suggest that he forged some kind of association with the earl of Stafford, lord of the borough. Although no details of such a connexion are recorded, it is possible that one arose out of legal work undertaken by him in the central courts for the earl or his local officials. Hamme continued to be active in the central courts in the 1430s, accepting briefs from such clients as the abbot of Bayham. Indeed, he appeared for the abbot on a number of occasions, most notably during the Michaelmas term of 1433, while he was once more attending Parliament, this time as a representative for New Shoreham.
