Remarks:
HUGH DE MORTIMER, youngest son of Ralph de Mortimer of Wigmore, by Gladys his wife, daughter of Llewellyn Prince of Wales.(Pat. 39 Hen. 3. p.2.m 6). He adhered to Henry III against the Barons, and having lost three good horses at the siege of Kenilworth Castle, had a grant of 40 marks to recompense him.(Rot.Fin.50 Hen. 3.m 1). Sheriff of Salop and Staffs 1272-3.(Rot. Pip.1 Edw.1).
He married shortly after 24th July 1255, Agatha de Ferrers, 6th daughter of William Earl of Derby, and one of the seven coheirs of her mother Sybil, sister and coheir of Walter Marshall Earl of Pembroke.(Pat.39 Hen. 3 p 2.m 6; Mon. Ang. I:727a a 20). By her he had issue,
I. HENRY, son and heir, born about 1266 (being 40 years of age at his mother's death).
II. HUGH, living 14th April 1300, when he was commissioned by his mother to sue for her purparty of the Marshal lands in Ireland.(Cl.28 Edw.I.m 101).
Hugh de Mortimer (husband of Agatha) died shortly before 23rd June 1273, when his kinsman Ralph son of Roger de Mortimer of Wigmore was appointed Sheriff of Salop and Staffs in his place (Rot.Fin.1 Edw.1.m 25). His widow who inherited a seventh of of fourth part of the large estates of the Marshals, including a sixth of Luton, Beds., a seventh of Sturminster-Marshal, Dorset, and lands in Wexford, Kildare and Kilkenny, died shortly before 12th June 1306.(Esch.34 Edw.I. no 38).
As we can see, the chronology here is fine for Hugh de Mortimer and his wife, Agatha de Ferrers, to be the parents of Iseult de Audley, who I judge was born say 1260/5. It doesn't work at all for Iseult to be the daughter of Hugh de Mortimer's nephew, Edmund de Mortimer, who was born about 1252. I might add that Agatha de Ferrers was evidently born in the mid to late 1230's.[JohnFaye (8 Jun 05).FTW]
