William Boynton (c. 1400 - 1428)
William Boynton, eldest surviving son of Sir Henry Boynton was born about 1400, his elder brother Thomas having died sometime before April 1422 without heir of his body. [43]
In 1425, William petitioned the king for the return of his father's lands. [44] He was evidently successful in reclaiming his lands, because on 5 November 1427, William Boynton, esquire, granted to Henry Percy, earl of Northumberland, Ralph Neville, earl of Westmorland, John Fenwick, William Strother, William Harding, esquires, and John Slegh, chaplain all his manors in the County of York. [45]
In the traditional pedigrees of the Boynton family, William Boynton is said to have married "Jane daughter of Simon Harding." It appears however, that he married Elizabeth, daughter of Sampson Harding, of Beadnell, Northumberland, who was M.P. for both Newcastle and Northumberland eleven times between 1382 and 1421. [46] William Harding, eldest son of Simon, was one of William Boynton's feoffees in November 1427.
William Boynton died shortly before 15 October 1428, when the writ of diem clausit extremum was issued to the escheator in Yorkshire. [47] No inquisition appears to have survived. Elizabeth was living in Hilary term 1448, when Elizabeth Boynton of Newcastle on Tyne, widow of William Boynton, son of Henry Boynton, knight, sued Christopher Boynton of Sedbury, Yorkshire in a plea of debt.
