Gruffudd ap Cynan ab Iago, king of Gwynedd

Gruffudd was born and grew up in Dublin, where his father had fled, probably following a 1039 coup. In 1075, Gruffudd sailed from Ireland to Anglesey and attempted to take control of Gwynedd, where his grandfather had ruled. After initial successes, he was forced to retreat to Wexford, in Ireland. In 1081, he again attempted to take Gwynedd. This time, after initial success, he was captured and imprisoned in Chester for at least 12 years. He eventually escaped, and seems to have participated in the Welsh revolt of 1094. Eventually Gruffudd gained control of Anglesey, and gradually, after 1099, he extended his control over the rest of north Wales. In 1114, Gruffudd submitted to Henry I, who had led a major campaign against him. Later in his life, Gruffudd’s sons continued to press into Meirionydd, Powys, and Ceredigion. A near contemporary biography of Gruffudd survives. (Pryce, ODNB “Gruffudd ap Cynan”)

Relationships

Father: Cynan ab Iago ab Idwal.

This relationship is shown by Bartrum (“Gruffudd ap Cynan 1”) and given by Pryce (ODNB “Gruffudd ap Cynan”). Brut y Tywysogion (s.a. 1073, s.a. 1096, etc.) calls him “Grufud uab Kynan.” In Brut y Tywysogion (s.a. 1079) and Annales Cambriæ (s.a. 1073), he is referred to as the grandson of Iago, presumably because Gruffudd’s father, having spent most of his life in Ireland, was not well known.

Mother: Radnaillt of Dublin.

This relationship is shown by Bartrum (“Gruffudd ap Cynan 1”), and given by Pryce (ODNB “Gruffudd ap Cynan”). The ultimate source of the information is HGaC § 1. This source is often unreliable, but probably right about this relationship. (See Jones, p. 46; Baldwin, LaI).

Spouse: Angharad ferch Owain ab Edwin (Died 1162). Married about 1095.

This relationship is shown by Bartrum (“Gruffudd ap Cynan 1”) and given by Pryce (ODNB “Gruffudd ap Cynan”).

Spouse: a daughter of Llychwy of Llanbeulan, Llifon.

This relationship is shown by Bartrum (“Gruffudd ap Cynan 1”).

Spouse: Perwyr ferch Brân.

This relationship is shown by Bartrum (“Gruffudd ap Cynan 1”).

(Complete source citations for facts about the children on this page are currently outside of the scope of this project. Most information below comes from Bartrum.)

(Early Welsh sources usually don’t distinguish mistresses from wives legally married according to church law.)
