"In 1416, June 16, the Bishop of Worcester obtained a license to grant 14 messages and 2 carucates(+) of land in Throckmorton, parcel of the Manor of Fladbury, to Sir John de Throckmorton, to be held of the bishop at a fee farm rent. This was probably the estate which the bishop held in demesne in the twelfth century." (Victoria History of Worcestershire, vol. III. page 356.) On this grant Leland statement, often quoted, was based.
It will be seen on perusal of the text that the Throckmortons were the principal owners of land in Throckmorton from 1175, and possibly long before. Robert de Throkemerton, in 7 Edw. III (1335), in a charter at Coughton, is spoken of as Lord of Throckmorton.
There is no definite or documentary evidence as to the descent of John de Throkemerton of 1175, unless one accepts the following taken from the Feudal Aids of Worcestershire, 20 Edw. III:
".... Johannes Hyband tenit unam hidam in Throkemorton quam Henricus filius Johannis. Adam filius Roberti?? Willieli??us filius Jocelin et Edwardus filius Gernassi quondam tennerunt."
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."
