He is the titular saint of Braunton (Devon), where William Worcestre and Leland say he was buried. Some identify him with Brynach, the Welsh missionary of the 6th century. Feast (at Exeter and according to William Worcestre): 7 January, while the feast of Brynach is 7 April. This makes the identification of the two unlikely.
