Resident for a while in Meifod where he was associated with St Beuno, to avoid further trouble from his family he set up a hermitage on Ynys Tyslio in the Menai Straits. From there he evangelised Ynys Mon (Anglesey) for seven years before returning to Meifod where he became Abbot and rebuilt the abbey church and founded a second church there - the Eglwys Tysilio.
After the death of his brother, his sister-in-law, Queen Gwenwynwyn, wanted to marry him and set him upon the throne. Faced with the persecution of the monastery that followed his refusal, he left for Brittany with a handful of followers, travelling through Dyfed to Saint-Suliac where he established a monastery. He died and was buried at the abbey there in 640.
by whose grace Tysilio, kindled with the fire of your love,
became a burning and a shining light in the Church:
inflame us with the same spirit of discipline and love,
that we may ever walk before you as children of light;
through Jesus Christ our Lord.
