Arthur, Prince of Wales
Tyndale is recorded in two genealogies as having been the brother of Sir William Tyndale of Deane, Northumberland, and Hockwold, Norfolk, who was knighted at the marriage of Arthur, Prince of Wales to Catherine of Aragon. Tyndale's family was thus descended from Baron Adam de Tyndale, a tenant-in-chief of Henry I. William Tyndale's niece Margaret Tyndale was married to Protestant martyr Rowland Taylor, burnt during the Marian Persecutions.
