Events
Date of Birth: about 930.
This estimated date is given by Bartrum (EVWG “Early Series [42]”).

Relationships
Father: Owain ap Hywel Dda ap Cadell (died 988).
This relationship is shown by Bartrum (EVWG “Early Series [42]”), and given by Maund (1991, pp. 17-20; 2000, p. 55), and by Thornton (ODNB; 1997, p. 569). It is recorded in Brut y Tywysogion and in Annales Cambriæ.
(supposed) Mother: Angharad ferch Llywelyn ap Merfyn.
This relationship is shown by Bartrum (EVWG [42]). Bartrum in EWGT (p. 141) notes that later genealogists asserted this relationship as a way to give Bleddyn ap Cynfyn a claim to the rule of Powys through descent from Merfyn ap Rhodri Mawr, who was supposedly allotted Powys in the division of the realm of Rhodri Mawr. Thornton (1997, p. 569) notes that the evidence for this marriage is late and unreliable.
Spouse: unknown.
