As tracing the title of the property back to the time of Domesday, we know from contemporary documents that Henry de Throkemerton was the son of John de Throkemerton, who was taxed two marks in 1175, and that Adam was the son of Robert, who was the son of Henry: but we must assume that William was the son of Joscelin, who was the son of Edwardus, who was the son of Gervase who held land in 1086 in Throckmorton.
"The bishop, who at this time held a manor in Throckmorton, in demesne, had other tenants at Throckmorton. Norman held half a hide of land and Osmund the Chamberlain half a hide.?? In a later survey the heir of Osmund, the Chamberlain, was holding at Throckmorton a hide and a half of land, which Osmund, son of Gervase, held of him. Bishop John about 1151 confirmed this tenement to Osmund for the service Malgetus did for it."
