The history of St Brannoc is confused – some sources conflate him with Saint Brynach, however Exeter Cathedral celebrates the feast of Brynach on 7 April and that of Brannoc on 7 January so it is unlikely that they are the same saint.
The identity of St Brannoc is shrouded in mystery – some sources blur the lines between him and Saint Brynach, but Exeter Cathedral's separate commemorations of their feasts on different dates imply they might be two separate saints.
