he single-handedly slew twelve men in that fight. After that Klakk-Harald gave him his daughter, who was called Ingibjorg. They had two children: Gudthorm and Ragnhild." The narrative then identifies Ragnhild as the wife of Halfdan the Black and mother of Harald Fairhair of Norway. The Heimskringla changes the name of Harald Klak's daughter but the given lineage remains the same. "Ragnhild's mother was Thorny, a daughter of Klakharald king in Jutland, and a sister of Thrye Dannebod who was married to the Danish king, Gorm the Old, who then ruled over the Danish dominions."
