ANNA or ONNA
(c.635-54)Son of Eni; godfather of Cenwalh, exiled king of Wessex. Onna was later exiled himself and afterwards killed in battle by Penda (HE III, 18; ASC 654).
He was buried at nearby Blythburgh, where his tomb was still being venerated by pilgrims in the twelfth century (Liber Eliensis).
King Anna might be identified with the 'King Æþelmund' of Abbot Folcard's Life of St Botolf . Certainly the form of the compound name Æþel-mund is precisely consistent with those of all Anna's brothers, Æþelric, Æþelhere, and Æþelwald. As Anna (Bede's spelling) or Onna (the form in the Anglo-Saxon Chronicle) seem likely to be variants of the same nickname, the fuller version of his name may well have begun with Æþel.
If Anna is identifiable with Folcard's Æþelmund then is queen may have been named Sæwara.
He was father of a saintly progeny, St Jurmin, St Seaxburh, St Wihtburh, St Æthelburh, St Æthelthryth, and a step-daughter, St Sæthryth.
