Thanks, Doug! Of interest, the wife of Anthony-814 was the sister of his cousin Joan Halle's husband, Sir Thomas Wriothesley, Garter Principal King of Arms.
Sir Thomas (329) also had a daughter Elizabeth* who married Morris/Maurice Blount, younger son of Sir Edmund (sometimes transcribed as Edward, but daughter's will, his own & father's ipms, and multiple leases all have Edmund) Blount of Mangotsfield and his wife Margaret Seymour. The pedigree below supports that John's wife, Margaret Blount, was also daughter of Edmund and Margaret Seymour, as suggested by her will, the description of John's arms in Cirencester church, and the 1521 quitclaim of her husband and son to some of Isabel Williams Seymour's property in the old city of Bristol near St. John's Gate. So we have the not unusual case of two siblings marrying two siblings.
*Confusingly she is called Elizabeth Higford, widow of Thomas Higford in Christiana's will 1504. Did she marry twice or were they different daughters?
Anne Hungerford who married a Langley is said in History of Parliament (p525) to be Sir John's sister rather than daughter. Is there a source for her being daughter to John?
