Peulan

Saint Peulan was a Welsh saint of the early sixth century, a son of Paul Hên (Paulinus), a saint of south Wales who taught Saint David. His name means "little Paul". His sister was Saint Gwenfaen, venerated at Rhoscolyn, and his brother Gwyngeneu, who had a chapel on Holy Island, now vanished.

He was a disciple of Saint Cybi, with whom he came from Cornwall to Anglesey, and he is counted among the twelve "seamen" who made up Cybi's family. Tradition says he founded the first church at Llanbeulan in the year 630; the oldest parts of the present building date from the twelfth century, and the church is now closed. His feast in the Welsh calendars is given as 1 or 2 November, and at his church it was also kept on 17 March. His holiness was recognised locally, without formal canonization; he is a saint of the undivided Church.
