In 1406 Gyllyng and Richard Benge, whose wives were sisters, conveyed to feoffees their wives’ interest in the manor of Hamwold, near Sandwich. Four years later Gyllyng was acting as Benge’s executor. He owned an inn in Sandwich, and his appointment as deputy butler (a post he was holding when returned to Parliament for the second time) also suggests a personal involvement in the wine trade.4CP25(1)112/266/317; E364/44 m. Ad; Boys, i. 51; Sandwich Black bk. f. 3d.
In 1416-17 Gyllyng was sent by the Cinque Ports to Yarmouth with a batch of writs alleging breaches of the Ports’ rights at the annual herring fair.5Romney assmt. bk. 2, f. 88d. He is not recorded after the end of his term as deputy butler in 1418. A benefactor of St. Mary’s church, Sandwich, he paid for the glazing of its north window, and, presumably as a testamentary bequest, he also gave the church the sum of £20 and 10s. a year for its fabric.6Boys, i. 372.
