Through his marriage to Gilbert Forster’s widow, Turnaunt took control of considerable property and fulling interests in Winchester. His main business was in the finishing of cloth: one of the two tenters attached to the city fulling mill at Coitebury was let to him for 6s.8d. a year from 1416 until his death;
At the parliamentary elections held at Winchester in 1413 Turnaunt stood surety for the attendance in the Commons of a fellow clothier, Mark le Faire, and as bailiff he notified the sheriff of Hampshire of the results of the elections of March 1416. His own first return to Parliament occurred within a few days of the end of his bailiffship. It was a rare occurrence for a mayor of Winchester to be elected to Parliament while in office, but it was during Turnaunt’s first mayoralty in 1419 that he was returned for the third time. At an unknown date in 1421 or 1422 he rode to Southampton with the then mayor, Richard Bolt, and 12 other of the ‘best men’ of Winchester, seeking to resolve a disagreement with a messenger of the Chancery. (He may well have had trading interests there for he was a feoffee of property in the port as well as at Winchester.) Then, eight years later, he received travelling expenses for going with the mayor and John Bye ‘pro cc. marcis domino Henrico Cardinali’ (possibly a loan to the Crown negotiated by Cardinal Beaufort). Meanwhile, in the Parliament held at Leicester in 1426, he had acted as proxy for the abbot of Hyde. In June 1432, when up at Westminster for his last Parliament, Turnaunt provided securities at the Exchequer for the newly appointed alnagers of Hampshire.
That same year Turnaunt’s property in Winchester was reported by a local jury to be worth £2 p.a., but this was probably an underestimate, for in November 1430 he had been assessed at 50s. by the collectors of a fifteenth, a figure suggesting that he was then the wealthiest layman living in the city.
