The Gerards were a well established Norwich family, two members of which had represented the city as MPs before Henry VI’s reign, but John’s place in the family tree is not known.
Both Heydon and Dam were lawyers, and Gerard must have been another member of the legal profession. He appears not to have practised any trade, was usually styled a ‘gentleman’ and enjoyed sufficient status in Norfolk to be called upon to swear the oath to keep the peace administered throughout the country in 1434.
By then Gerard had served as mayor of Norwich, having begun his career as an office-holder in the city in 1422, if not earlier. His first known office was that of one of the city’s sheriffs, although he was certainly an alderman (in which capacity he represented Wymer ward) by 1424,
Gerard stood for election to the first of his six Parliaments shortly after concluding his term as sheriff. While attending the assembly of 1423 he and his fellow MP, Richard Moneslee*, also his companion in that of 1432, took the opportunity to take legal action against the City of London, in connexion with certain customs and tolls it had imposed on merchants from Norwich. Apart from their expenses for this suit, both men received 2s. per day while MPs. Gerard took like wages for the Parliament of 1425, although significantly more (40d. per day) for those of 1432 and 1435.
The Crown had seized the liberties (finally restored in December 1439) in the wake of the disputed mayoral election of 1437. According to a certificate filed by members of a faction led by Thomas Wetherby*, Gerard and eight other aldermen had assembled a large mob to prevent them from attending the election, which had degenerated into a ‘riot’. Although it is impossible to take the certificate’s claims at face value, Gerard and other opponents of Wetherby appeared before the royal council six weeks afterwards, no doubt to explain their conduct.
Gerard and Wetherby were still at odds in the early 1440s, when a Norwich jury indicted five of Wetherby’s servants. According to the indictment, in October 1441 these servants and some 40 others, acting at the behest of Wetherby and the prior of Norwich, had assaulted and imprisoned the mayor, William Ashwell*, and several other citizens, including Gerard. Already that year the prior, with whom the city was engaged in a long-running jurisdictional dispute, and who had allied himself with Wetherby and the de la Pole affinity, had begun legal proceedings against Ashwell, Gerard and other aldermen.
By that date, Gerard had entered the last few years of his life, although he appears to have remained active until his death. In the following month he made a release of lands at Buckenham Ferry, Carleton and elsewhere in the Norfolk hundred of Loddon to a group of feoffees, probably in the capacity as a trustee of Sir Thomas Kerdiston*, who had died at Norwich the previous summer. Ironically, one of Kerdiston’s heirs was Alice de la Pole, marchioness of Suffolk, and among those to whom Gerard was obliged to make the release was William Prentys, who had allegedly helped Heydon to oppress the city a few years earlier.
