• Notes

  Cynan ab Iago (c. 1014 - c. 1063) was a Welsh prince of the House of Aberffraw sometimes credited with briefly reigning as King of Gwynedd. His father, Iago ab Idwal ap Meurig, had been king before him and his son , G r u f f udd, was king after him. Iago was King of Gwynedd from 1023 to 1039 but was killed (possibly by his own men) while Cynan was still young. The throne was seized by Gruffydd ap Llywelyn, a member of a cadet branch of the royal dynasty. Cynan f l e d t o I r eland and took refuge in the Viking settlement at Dublin. He m a r r i e d Ragnailt, the daughter of its King Olaf Sigtryggsson and grandda u g h t e r of King Sigtrygg Silkbeard. Ragnailt appeared on the list of the " F a i r W o men of Ireland" in the Book of Leinster and was also descended f r o m B r i an Boru.
