King of East Anglia c640?-654
Anna was the second of the sons of Eni to assume the mantle of king of the East Angles and named by the Venerable Bede as "a man of true religion, and altogether noble in mind and deed."
Anna was to gain the the throne as a consequence of the death of his brother Ecgric at the hands of Penda of Mercia and the kingdom of East Anglia continued to live in fear of the ravages of the pagan Mercian. This did not prevent the pious Anne from giving refuge to king Cenwal of Wessex when Penda forced him from his kingdom. But such an act was to attract the emnity of Penda and we have the authority of Florence of Worcester records that in the year 654 Anna was slain by Penda, the third king of East Anglia to die by that warlord's bloody hands, and succeeded by his brother Aethelhere.
Anna was twice betrothed but was never blessed by any sons but rather by a number of daughters including Sexburga, Etheldreda, Withburga and Ethelburga who were to become simlarly noted for their piety and saintliness.
