誰が Sigurd the Crusader と結婚しましたか？

Sigurd the Crusader (Old Norse: Sigurðr Jórsalafari; Norwegian: Sigurd Jorsalfare; 1089 – 26 March 1130), also known as Sigurd Magnusson and Sigurd I, was King of Norway from 1103 to 1130. His rule, together with his half-brother Øystein (until Øystein died in 1123), has been regarded by historians as a golden age for the medieval Kingdom of Norway. He is otherwise famous for leading the Norwegian Crusade (1107–1110), earning him the eponym "the Crusader", and was the first European king to participate in a crusade personally.

Bjaðmunjo Mýrjartaksdóttir (Gaelic: Blathmuine ingen Muirchertach; fl. 1102/1103) was a daughter of a Muirchertach Ua Briain, High King of Ireland. In 1102, whilst still a child, she was married to Sigurðr, son of Magnús Óláfsson, King of Norway. At this time, Magnús appears to have been in the process of setting up his son as king over the Earldom of Orkney, the Kingdom of the Isles, and the Kingdom of Dublin. The marriage temporarily bound Muirchertach and Magnús together as allies before the latter's death the following year. Sigurðr thereupon repudiated Bjaðmunjo, and left for Scandinavia, where he proceeded to share the Norwegian kingship with his brothers.
