 It is therefore possible that when Ælfwald died, Alberht continued the dynastic line, being a direct descendant or from a cadet line, and accepted a division of power with a Mercian royal representative in order to continue the rule of the Wuffingas.Beonna's seniority in this arrangement is suggested by the large number of coins bearing his name and by the co-operation between the East Anglians and the Mercians in the Battle of Burford Bridge against Cuthred of Wessex in 752.Beonna may also be connected with Beornred, who for a few months ruled Mercia after Æthelbald's assassination in 757.
