G Andrews Moriarty has a pedigree in Family Tracts Vol 18 and vol 39, one of which givesThrockmortons from 1175 to 1470 odd.  This ends with a family of Throckmortons of Lone, Glos which has a pair of Johns dying one, executed, in 1460 and the other in 1473; my thought is that probably the earlier of these is the subject of this record.  sNeeds more investigation.
