This John Wesenham was probably a nephew of another John (d.c.1384), the influential merchant capitalist and financier of Edward III’s reign, belonging to the less important branch of the family which resided in Lynn, where his father, who had entered the freedom of the borough in 1349-50, served as chamberlain in 1356-7.
Some years previously, in July 1402, Wesenham had been included among the burgesses of Lynn required to undertake, each on pain of a penalty of £100, not to molest their overlord, Bishop Despenser of Norwich, or any of his officers, following serious disturbances in the town. Although one of the potentiores, he avoided involvement in the constitutional struggles which divided the people of Lynn in the period from 1411 to 1416, apart from being nominated as an elector to the second Parliament of 1413, and thereby appearing to support the return of two inferiores. He was listed as a witness to the parliamentary election indentures of 1420, 1421 (May) and 1425, and on the last two occasions also acted as mainpernor for the attendance of Bartholomew Sistern and John Copnote respectively.
