The Poultneys owed their wealth and lands to Sir John Poultney (d.1349), a merchant who had made his fortune in the city of London and invested in property in Cambridgeshire, Hertfordshire, Middlesex, Kent and his native Leicestershire. These substantial estates, along with holdings in the City worth some 100 marks p.a., descended to Sir John’s heirs, and by 1524 the then head of the family, Sir Thomas Poultney enjoyed a landed income of at least £160 p.a.
Given the size of his inheritance, the MP of 1431 is a surprisingly obscure figure. He is not known to have held any official position apart from his seat in the Commons, but his non-involvement in public affairs is probably at least partly explained by the time he spent abroad in France. He is first heard of in the late spring of 1414 when he, his father, two younger brothers and three others were indicted for ambushing and attempting to kill Richard Chetwynd at Hopwas Hays in Staffordshire in the previous February. In the same spring, he and several accomplices, probably Poultney tenants or servants, were indicted for ambushing and wounding Thomas Wylkyn and Thomas Hayward, again at Hopwas Hays, in July 1412. In response to the first indictment, the Poultneys paid fines of 40d. each to recover the King’s grace; as a result of the second, Thomas and his associates came before the court of King’s bench. Appearing there on 1 June 1414, they pleaded not guilty, secured bail and were subsequently acquitted by an assize jury sitting at Lichfield.
It is not certain when Poultney succeeded his father, although he had probably come into his own by the mid 1420s when he was involved in litigation in the court of common pleas.
Although associated with Leicestershire for much of his career, Poultney had taken up residence in Hertfordshire when he was distrained for knighthood in 1430. He entered Parliament late in life, for he was almost certainly dead by December 1433. In that month his heir, John Poultney, demised the manor at Ospringe to John Thornbury* and his wife Margery, to hold for a nominal rent during her lifetime and thereafter by the payment of 20 marks p.a. to Poultney from Thornbury.
