From Dictionary of National Biography, vol. XII, edited by Sidney Lee, New York, 1909, p. 1015:

"Maredudd [ap Owain]'s only son, so far as is known, died before him. But so great was the prestige he acquired in his brief reign that his daughter, Angharad, was regarded, contrary to ordinary Welsh custom, as capable of transmitting some royal right to her descendants. H first husband, Llywelyn ap Seisyll [q. v.], ruled Gwynedd from about 1010 to 1023, their son, the well-known Gruffydd ap Llywelyn [q. v.], from 1039 to 1063. By her second marriage with Cynfyn ap Gwerstan she had two other sons, Rhiwallon and Bleddyn, of whom the latter, with no claim on the father's side, ruled Gwynedd and Powys from 1069 to 1075 and founded the mediaeval line of princes of Powys.
