A minor royal official, John must have owed his seat in the Commons to his connexion with the Crown. He had a peripatetic career, for a royal pardon he received in 1452 referred to him as ‘of Reading’ and ‘late of’ Hereford, London, Dauntsey and Malmesbury.
Omitted from the pardon is any reference to Monmouth’s position as one of Henry VI’s serjeant-at-arms, to which he had been appointed in late 1444, presumably because he was not then in jeopardy from any lawsuits against him in that capacity. Appointed for life, he was certainly still in office in 1450-1,
Upon becoming a serjeant, Monmouth received daily wages of 12d. from the issues of Herefordshire and Wiltshire, two of the counties with which he was linked, as well as the livery of an esquire of the Household.
It is far from certain that the serjeant-at-arms was the lawyer of the same name who was active at Westminster during the second half of the fifteenth century. In 1451, perhaps shortly after embarking on his career, this John Monmouth was sued (as ‘late of the parish of St. Clement Danes outside the bar of the New Temple’) in the court of common pleas over debts allegedly owed to David John. Later, by 1465 until at least 1476, he was an attorney in the same court in cases emanating from Wiltshire and other counties.
