Courtesy of fantastically full family tree cf.:

Hughes of Gwerclas 1/2/3/4:

Little is known of Cynfyn. His fame, like that of many of his descendants, was only the reflection of the fame of his distinguished wife. There is no evidence that he ever attempted to rule in the right of his wife as did her first husband. The sons of Cynfyn and Angharad were Bleddyn and Rhiwallon. The pedigree of Cynfyn which appears in Vol 1, p 63 of the Historical Manuscripts Commission, London, 1898, extends back through twenty-two generations to Beli Mawr and Anna through their son Llud. Prof Lloyd thinks that it is mythical. It is certainly incomplete. It would require many more than twenty-two generation to cover the period of more than one thousand years. In the History of Radnorshire it is stated that Cynfyn was the son of Gwerstan and the grandson of Gwaethfoed Fawr. [The Weaver Genealogy]
