Born in the early years of Henry IV’s reign, Symon was admitted to the freedom of Exeter in June 1421, paying the common entry fine of £1.
Symon was thus not without administrative experience when in 1432 he was chosen to represent the city in Parliament in peculiar, if largely obscure circumstances. The sheriff of Devon’s original indenture, sealed at Exeter castle on 15 Apr., named John Salter I* and the lawyer Adam Somaster* as the city’s elected representatives. However, on the schedule accompanying the indenture the name of the less distinguished Symon replaced that of Somaster and it was he who in the event rode to Parliament and drew £3 18s. 4d. in wages for his labours. As Symon’s colleague Salter was paid £4 16s., it is possible that as a result of the confusion surrounding his election he arrived late at Westminster and consequently missed part of the nine-week session.
The full extent of Symon’s property has not been established, but for some years he rented property in the parish of St. Sidwell’s from the Exeter authorities, while it was evidently his marriage that had brought him a building in the High Street just outside the east gate and various closes of land which he conveyed to his fellow alderman Thomas Jolyblood in about 1427.
