The earlier biography failed to identify this MP.
There is a possibility, however, that he was the John Sewall who had been appointed in July 1410 as one of four messengers of the Exchequer, with a daily wage of 4½d. for life. Confirmed in office at the beginning of the reigns of Henry V and Henry VI, he was assigned livery at the great wardrobe to wear at the latter’s coronation in 1429.
Sewall the messenger was engaged in the business of Parliaments to the extent that he delivered summonses to the Lords and writs to the sheriffs for those of 1423, 1433 and 1437, and he was sent to attend on the treasurer while Parliament was at Reading in January 1440.
There is, however, nothing in all this activity to connect Sewall the messenger with west Sussex and the borough of Midhurst.
