About Nest verch Iorwerth

Please see Darrell Wolcott: The 'Next Heir' of Morgan of Caerleon; (Steven Ferry, September 18, 2020.)


Late in June 1175 Iorwerth came to an agreement with the Lord Rhys, with whose support he regained Caerleon from King Henry. The recovery of Caerleon may also have had something to do with the sexual liaison between the king and Iorwerth's daughter, Nest Bloet, with whom the king had an illegitimate son, Morgan (surnamed Bloet, from his being brought up in the family of Nest's husband, Ralph Bloet (d. 1199) of Silchester).


HENRI d’Anjou, son of GEOFFROY "le Bel/Plantagenet" Comte d'Anjou et de Maine & his wife [Empress] Matilda [Maud] of England (Le Mans, Anjou 5 Mar 1133-Château de Chinon 6 Jul 1189, bur Abbaye de Fontevrault[370]).

Mistress (5): NESTA, wife of RALPH Bloet, daughter of ---.

King Henry II had one illegitimate child by Mistress (5): 12. MORGAN ([1180/89]-after 1213).

Robert de Graystane´s early 14th century History of the Church of Durham records the election as bishop of Durham in 1213 of “Morganus frater Regis Johannis et Galfridi archiepiscopi Eboracensis, præpositusque Beverlacensis”, that his appointment was blocked by Rome because he was born “spurius...Henricus pater eius” to “uxore...militis...Radulphi Bloeth”, and that the Pope offered to confirm the election if he declared that the king was not his father, which he refused to do[545]. Provost of Berkeley, Yorkshire 1201. Elected Bishop of Durham in 1213.

Morgan was an illegitimate son of King Henry II of England and Nesta, daughter of Iorwerth ab Owain, Lord of Caerleon. Nesta was married to Sir Ralph Bloet, who raised Morgan as his son. The date of his birth is unknown but presumed to be toward the end of King Henry's life.[1]
