Trillo

Saint Trillo (also called Drillo or Drel) was a Welsh saint of the sixth century, the patron and founder of the churches at Llandrillo in Denbighshire and Llandrillo yn Rhos (Rhos-⁠on-⁠Sea) in Conwy, in Gwynedd.

According to Enwogion Cymru, he lived in the early sixth century and was one of the sons of Ithel Hael. He was nobly born in Brittany and came to Wales with his brothers Saints Tegai and Twrog as a disciple of Saint Cadfan, who later admitted him to the monastic life. He became an abbot and church-⁠founder, noted for his holiness. He was buried on Bardsey Island. His church at Llandrillo contains stained glass of the 1920s showing scenes from his life. He is commemorated on 15 June as a saint of the West before the Great Schism (a saint of the undivided Church), by the New Calendar.
