Research Notes:

Octa or Octha was King of Kent during the 6th century [some sources show the period 516 to 540].... Despite his shadowy recorded history Octa made an impact on the Britons, who describe his deeds in several sources. The 9th-century Anglo-Saxon Chronicle, one of the most important sources for this period of history, does not mention Octa. It does, however, mention Hengist and gives Oisc as his son. However, Bede's Ecclesiastical History of the English People, completed around 731, names Octa as the son of "Orric, surnamed Oisc" and the grandson of Hengist....

Octa also appears in the Historia Brittonum, a 9th-century history of the Britons. According to the narrative, Hengist, who had settled in Britain with the consent of the British king Vortigern as defence against the Scots, sends for his sons Octa and Ebusa to supplement his forces. Octa and Ebusa subsequently raid Scotland.

After Hengist's death Octa becomes king of Kent.
