Between 652 and 653 Bishop Brigilsus was consecrated Bishop of Dunwich aka East Anglia.
Around 670 Bishop Brigilsus died.
Bede. This synod was held in the year from the incarnation of our Lord 673. In which year, Egbert, king of Kent, died in the month of July; his brother King Hlothhere of Kent succeeded him on the throne, which he had held eleven years and seven months. Bisi, the bishop of the East Angles, who is said to have been in the aforesaid synod, was successor to Boniface, before spoken of, a man of much sanctity and religion; for when Boniface died, after having been bishop seventeen years, he was by Theodore substituted in his place. Whilst he was still alive, but hindered by much sickness from administering his episcopal functions, two bishops, Ecci and Badwin, were elected and consecrated in his place; from which time to the present, that province has had two bishops.
