Cybi

[pronounced Kubby] (Lat. Chebius, or Kebius), a Welsh saint, was a younger cousin of St. David. He was present at the synod of Brefi, and his memory, near Llanddewi Brefi, the place where it was held, is preserved in the name of the Church of Llangybi. The churches of Llangybi, near Caerleon, and Llangybi, in Carnarvonshire, were founded by him. He is especially distinguished as founder of a society at Caergybi or Holyhead, in Anglesey. As presiding over this he was styled, according to the practice of the time, a bishop, though he never had authority over a diocese. The day of commemoration is variously given as November 6 and November 8.
