Cybi

Saint Cybi (in Welsh) or Saint Cuby (in Cornish) was a 6th-century Cornish bishop, saint and, briefly, king, who worked largely in North Wales: his biography is recorded in two slightly variant medieval 'lives'.

Life in Cornwall

According to the 'Life of Saint Cybi', this saint was the son of Salomon, a 'warrior prince', generally thought to have been a King of Cornwall. In the 'Bonedd y Saint', his father's name is given the Welsh form, Selyf. He was raised as a Christian and, in early life, went on a pilgrimage to Rome and Jerusalem. He became a priest and was consecrated as a bishop, before he arrived home to find that his father was dead and he was King of Cornwall. Cybi politely declined the throne and, instead, travelled through his kingdom, preaching to the people and building churches at Duloe, Tregony, Cubert and Landulph.

Life in Wales

He then moved on to south Wales, founding churches at Llangybi-ar-Wysg between Usk and Caerleon in Monmouthshire, and Llanddyfrwyr-yn-Edeligion, before spending some time in Ireland. He eventually sailed for north Wales, settling at Llangybi on the Llŷn peninsula. Off Anglesey, King Maelgwn Gwynedd gave him the old Roman fort at Holyhead (subsequently known, in Welsh, as Caer Gybi, "Cybi's Fort") on Holy Island (thence called Ynys Gybi, "Cybi's Island"). He founded a large and important monastery there.
