Note: The claim that Sionet, daughter of Rhiwallon ap Cynvyn, was mother to Rhys "Sais" ap Ednyfed, and that another daughter of Rhiwallon, Gwladys, married Rhys ap Tewdwr, Prince of South Wales, virtually established the assumption that Rhiwallon was the son of Cynvyn ap Gwrystan either by an earlier marriage or by illegitimate birth, inasmuch as his mother could hardly have been Angharad verch Maredydd who didn't marry Cynvyn ap Gwrystan until 1023, when her first husband died. It is also likely that Cynvyn's daughter, Gwenfyn, who married Iestyn ap Gwrgan was born prior to 1023. Therefor Rhiwallon and Gwenfyn are listed arbitrarily for the sake of this compilation as children of an earlier marriage of Cynvyn. The claim as a result of previous temple work that this couple also had a son Caradoc is not indicated by the genealogical souces so far quoted.
