The Anglo-Saxon Chronicle does not mention Eowa; though it does date Penda's reign as the thirty years from 626 to 656, when Penda was killed at the battle of the Winwaed.
Den anglosaxiska krönikan nämner inte Eowa, men den daterar Pendas regeringstid till de trettio åren från 626 till 656, då Penda dog i slaget vid Winwaed.
