Cynyr Ceinfarfog, Lord of Caer Goch (born c.450)
Cynyr the Fair Bearded was a local lord in Dyfed, who lived at one of the three places called Caer-Goch (Caer Gawch) near Mynyw (St. Davids). He, apparently, also held Caer-Gynyr (later Caer Cai) near Bala in Penllyn and it was supposedly here that he raised the High-King Arthur as his foster-son. This followed Myrddin's (alias Merlin) agreement with the High-King Uther that his son should be brought up free from the knowledge of his onerous inheritance, with the Magician as his tutor. In later romance, Cynyr became known as Sir Ector. Cynyr's name is the equivalent of the Irish, Connor, and indicates that he was one of the many Irish immigrants who colonized Dyfed in the mid-5th century. In fact, he appears to be identical to Prince Conchrad (son of Duí Tenga Uma, a late 5th century King of Connaught) who was St. Mo-Chop (Cybi)'s grandfather. Cynyr apparently married Princess Sefin, the daughter of St. Brychan, King of Brycheiniog, a monarch also of Irish origin; and also, Anna daughter of Vortimer Fendigaid, King of Gwerthefyriwg (Gwent). It is not quite clear which was the mother of his children. He is occasionally called Cynyr Wledig (the Imperator) or Cynyr Goch (the Red).
