and the Mercians.

Diuma was consecrated after 655 but his death date is unknown. It would appear to have been not long after this, as he was succeeded as bishop by Ceollach, whose own successor, Trumhere, was named bishop around 658. Bede refers to his episcopate as having been fruitful but short, after which he died in a place called in-feppingum in the territory of the Middle Angles. This place has never been definitely identified.
