Tecwyn

Saint Tecwyn is the patron and founder of Llandecwyn in the Welsh county of Gwynedd. He was a Welsh saint of the 6th century who founded the church at Llandecwyn early in the Age of the Saints. His name is sometimes written Tegwyn (feminine Tegwen), or in English Teckwyn.

He is believed to have been the brother of Saints Tanwg of Llandanwg, Twrog of Maentwrog, Tegai of Llandegai and Baglan of Llanfaglan. According to "Enwogion Cymru" he was the son of Ithel Hael of Brittany and came to Britain with Saint Cadfan, in the time of Vortigern, who sought wise and learned men from Gaul to renew Christianity in the island. The Breton language of that time was very close to the Welsh of the period. He was a member of the college of Bardsey, founded as a monastery in 516. An old Celtic cross was found in 1879 when the church was pulled down to build a new one. The church of Llanfihangel-⁠y-⁠traethau, a few miles to the south-⁠west, has a window with Saint Tecwyn and is the start of Saint Tecwyn's Way, a pilgrimage route between the two churches. He is commemorated on 14 September. He is honored as a saint of the undivided Church.
