Aldfrith of Northumbria [SEP] Heirs, death, and succession
Aldfrith was married to Cuthburh, sister of King Ine of Wessex; the marriage thus allied Aldfrith with one of the most powerful kings in Anglo-Saxon England. The "Anglo-Saxon Chronicle" records that Aldfrith and Cuthburh separated, and Cuthburh established an abbey at Wimborne Minster where she was abbess. At least two sons were born to Aldfrith, but whether Cuthburh was their mother is unrecorded. Osred, born around 696 or 697, succeeded to the throne after a civil war following Aldfrith's death. Little is known of Offa, who is presumed to have been killed after being taken from Lindisfarne in 750 on the orders of King Eadberht of Northumbria.
