Anderson/Olesen/Ottum/Draegni/Kilen

I am trying to find information about my great grandmothers family. Her name was Anna Sjursdotter Kilen. I have seen her last name spelled many ways. She was born in 1870 in Sogn Og Fjordane Norway. Her marriage certificate to Fred Anderson in 1898 lists parents as Sever (Sjur) Olesen and Kristi Draegni (also listed as Dregni, Drightne). She emmigrated to Wisconsin in the 1890's, from what I understand, she came alone. She married Fred Anderson and they lived in Dane County Wisconsin. Would love to find out anything I can about what farms her family lived on in Norway, and anything I can about her family in Norway. Family Search lists her fathers name as Sjur Olesen Ottum.
