What is "freawine"

Freawine, Frowin or Frowinus figures as a governor of Schleswig in Gesta Danorum and in the Anglo-Saxon Chronicle as an ancestor of the kings of Wessex, but the latter source only tells that he was the son of Frithugar and the father of Wig.

In the Gesta Danorum, Frowin was the father-in-law of Offa of Angel (presented as a prince and later king of Denmark), whose father king Wermund liked both Frowin and his sons Ket and Wig.

Frowin was challenged to combat by the Swedish king Athisl, and killed. He would later be avenged by his two sons Ket and Wig. However, the two sons fought against Athisl two against one, a national disgrace that was redeemed by their brother-in-law 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.
