Estrid Bjørnsdotter was the daughter of Björn Byrdasvend and Rangrid Guttormsdotter, who was a probable descendant of Tostig Godwinson, the brother of the last Anglo-Saxon King of England Harold Godwinson.
Ingebjørg Guttormsdatter was, alongside Ragna Nikolasdatter and Estrid Bjørnsdotter, known as one of the only two acknowledged queen consorts in Norway between the mid 11th century to the 13th century not to have been foreign princesses.
