Cynthia, according to GENi, Erik VII, "Segersäll" Björnsson, King of Sweden 945-995, is my husband Joe O'Callaghan's 33rd. great grandfather.
One of his wives Sigrid Tostesdotter (the Haughty) 950-1014 = Joe's 33 great grandmother. She was the daughter of Skoglar (Skagul) Toste. It seems that both husband and wife are related to my husband.
