The Gyne family possibly originated from Walberswick, since a court at nearby Dunwich fined a namesake of the MP from that town in October 1410. Later, in February 1413, another Dunwich court licensed William Gyne to conduct a property transaction with John Brooke of Sizewell, but the connexion, if any, between William and the future MP is unknown. John Gyne first features in local records of the early 1430s, by which date he was paying 26d. p.a. in rents to the corporation of Dunwich.
There is no evidence that Gyne held any office at Dunwich before September 1442, when he began his first term as bailiff. During this term, the King granted the keeping of the town’s fee farm to William de la Pole, earl of Suffolk, after the death of the previous holder, William Phelip†, Lord Bardolf, in 1441. The grant, of February 1443, was for ten years, beginning at Michaelmas 1442, and Gyne and Thomas Peers* acted as the earl’s mainpernors. Gyne features as a ‘merchant’ in the grant although a royal pardon he received four years later described him as a ‘yeoman’.
Following the dissolution of that Parliament in June 1450, Gyne survived for another year. Having drawn up his will on 13 June 1451, he had died by the following 31 July, when it was proved.
