About Ket of Angel
Ket and Wig appear in the Gesta Danorum (book 4) as the sons of Frowin, the governor of Schleswig. Wig also appears in the Anglo-Saxon Chronicle as the son of Freawine (Frowin), and an early Northumbrian genealogical collection makes him father of Bernic, ancestor of the kings of Bernicia This pedigree is though to have been borrowed, replacing Bernic of the Bernicians with supposed son Gewis, eponymous ancestor of the kings of Wessex.
Their father Frowin/Freawine was challenged to combat by the Swedish king Athisl, and killed. King Wermund who liked their father subsequently raised Ket and Wig as his own. They later avenged their father, but they fought against Athisl two against one, a national disgrace that was redeemed by their brother-in-law, King Wermund's son Offa, when he killed two Saxons at the same time, in "single combat". This event is referred to in Widsith as a duel against Myrgings.
