The identification of Plympton Erle’s most eminent parliamentarian of the fifteenth century is complicated by his alternate use of two surnames, but an Exchequer bill of 1428 leaves no doubt that John Silverlock ‘aultrement dit’ John Serle was in fact a single person.
An attorney, Serle alias Silverlock often acted in the courts at Westminster for his neighbours,
In the course of his career Serle made some powerful enemies in the locality, not least the wealthy Sir Robert Chalons† of Challonsleigh who claimed to have been ambushed and assaulted by the lawyer with an armed following of townsmen in September 1427. Litigation over the incident continued for several years, and possibly accounts for Serle’s absence from the Commons in the Parliaments assembled a month later in October 1427 and in 1429.
Serle was fully capable of abusing his superior knowledge of the law to his own advantage. When John (or Richard) Brackley, a yeoman of Plympton Erle, was challenged before the justices of common pleas to satisfy him under an obligation for five marks, Brackley claimed that the obligation had been made under certain conditions, agreed verbally, and maintained that as he was only ‘minime literatus’, the document had been read to him and expounded in English as containing the agreed conditions, whereupon he had sealed and delivered it to Serle in good faith. Serle, sensing his advantage over the uneducated man, denied that there had ever been any conditions attached and demanded full payment.
In his final years Serle employed a fellow lawyer, John Cokeworthy* (his former colleague as customs collector), as his receiver, but was forced to sue him for an account of his activities.
