There is a possibility that Thomas was related to John Tremayne†, the Cornish serjeant-at-law and sometime recorder of London who served as a j.p. in Hampshire, if only because when in 1386 John made a grant of his lands in the parish of St. Erth, Cornwall, he did so at Winchester.
By then Tremayne had moved more permanently to Winchester, where he set up in business. In 1443-4 he had five barrels of black soap, a grinding-stone, six bales of woad and a pipe of oil carried there from Southampton,
On 7 Aug. 1441 Tremayne had been formally exempted by the civic authorities of Winchester from having to take on the office of bailiff of the commons,
Tremayne’s property in Winchester included the messuage and garden which he and his wife acquired in the spring of 1444 from the former mayor, John Wryther*, who was planning to return to his native Sussex. This was a substantial holding situated in Wongar Street. Tremayne paid a rent of 7s. p.a. for the garden until 1454, when the property passed to William Sylvester.
