Dyfodwg
Dyfodwg, or Tyfodwg, was a 6th-century Welsh saint. He is one of the three saints from whom the ancient parish of Llantrisant takes its name, and possibly the patron of the parish church of Llandyfodwg in Glynogwr, between Blackmill and Gilfach Goch in Bridgend, Wales.
Some say he was a Breton monk, a disciple of Saint Illtyd of Llantwit Major. Llandyfodwg parish website asserts that some historians believe that Tyfodwg was a local chieftain promised sainthood by that monastery - the parish of Ystradyfodwg in the nearby Rhondda Valley has never had a church dedicated under the name of Dyfodwg, suggesting that the place was named after its chieftain. Rather, Ystradyfodwg's parish church is dedicated to Saint John.
According to Rice Rees Tyfodwg was one of the associates of Cadfan, though the family line in the Cambrian Biography, is inconsistent with known chronology. His patronal feast is kept on 25 June.
