Historians do not agree on Ecgberht's ancestry. The earliest version of the Anglo-Saxon Chronicle, the Parker Chronicle, begins with a genealogical preface tracing the ancestry of Ecgberht's son Æthelwulf back through Ecgberht, Ealhmund (thought to be Ealhmund of Kent), and the otherwise unknown Eoppa and Eafa to Ingild, brother of King Ine of Wessex, who abdicated the throne in 726.
