John Stourton's biography in The History of Parliament states, [1],
To his nephew, (Sir) John Stourton, he gave his 'good psalter which belonged to William his father', together with vestments of blue cloth of gold and plate and silk for his chapel, but the executors were warned that should the younger man not be satisfied with these bequests in respect of items that had been his father's, they should not allow him to receive them. To his niece, Margaret, and her husband, William Carent, Stourton bequeathed a gold rosary, and to the latter 'for his labour and friendship' £10 and a black horse. John Godewyne, executor of his will and also of that of his deceased brother, Master Richard, was to have £10 too. Stourton’s executors were also instructed to make a tomb at Dawlish Wake of ‘two images, one of a man armed and the other of a gentlewoman, designed for a memorial of John Keynes and his wife’ (probably the testator’s sister). The will, dated to Nov. 1438, prohibited any great expense at Stourton’s funeral: the amount usually spent on such occasions (up to £20) was to be distributed among the poor. He died on 16 Dec.
Stourton left three daughters, each by a different wife, and his estates were divided between them. The eldest, Cecily, the widow of John Hill†of Spaxton (for whom Stourton had acted as executor in 1434), was now the wife of Sir Thomas Kyriel of Sarrecourt, on the Isle of Thanet, currently making his reputation as a soldier; the second, Joan, was married to John Sydenham of Bridgwater; and the third, Alice, was aged seven and as yet unmarried. (Later she was wedded first to William Daubeney of South Ingleby, by whom she became the mother of Giles, 1st Lord Daubeney, and then to Robert Hill of Houndstone, nephew of his namesake of Spaxton). Stourton’s widow married secondly Sir John Beynton of Hampreston, Dorset, thirdly William Wadham, and lastly William Carent (the same person as had previously been the husband of Stourton’s niece); she survived our MP by nearly 35 years, eventually dying in 1473.
