Urian was a Christian name customary in the St. Pierre family resident in Cheshire, and the MP himself may have belonged to the junior branch living at Coole in the hundred of Nantwich, whose principal holdings passed to an heiress in Richard II’s reign. Certainly, his early interests were in that neighbourhood: in October 1391 he stood surety for David St. Pierre (perhaps his brother) in connexion with the latter’s assumption of office as bailiff of the hundred, and he himself, similarly, was connected with the administration of Nantwich in 1402 and 1410. On the latter occasion he entered into recognizances with Henry, prince of Wales, to ensure the payment of arrears of revenue from the hundred.
By this time St. Pierre had married the sister of Sir Roger Acton who, having been sheriff of Shropshire in 1404-5 and 1409-10, was to be executed in 1414 for taking part in Sir John Oldcastle’s rebellion. In 1407 St. Pierre had purchased property in Shrewsbury, Coleham and Abbey Foregate and subsequently, on 31 Jan. 1408, had obtained admission as a burgess of Shrewsbury, ‘pro se et heredibus de corpore suo legitime procreatis’.
Two months after the conclusion of his second bailiffship (1430-1), St. Pierre served as a juror at Shrewsbury during the inquiry into liability to contribute to a royal aid. Since 1423 he had been acting as a coroner in Shropshire, but in February 1436, when he was said to be ‘too sick and aged’ to officiate, the sheriff was instructed to elect a replacement. He died before 15 Nov. the same year.
