Anglo-Saxon royal genealogies
A number of royal genealogies of the Anglo-Saxon kingdoms, collectively referred to as the Anglo-Saxon royal genealogies, have been preserved in a manuscript tradition based in the 8th to 10th centuries. The genealogies trace the succession of the early Anglo-Saxon kings, back to the semi-legendary kings of the Anglo-Saxon settlement of Britain, notably named as Hengist and Horsa in Bede's Historia ecclesiastica gentis Anglorum, and further to legendary kings and heroes of the pre-migration period, usually including an eponymous ancestor of the respective lineage and converging on Woden.
