Information about Great Grandmother

I was wondering if you had any information about my Great Grandmother Cornelia Petersen (Russell) Ray. I know she was born in Olso, Norway June 25, 1847 and died Aug 22, 1928. She married Bateman Thomas Ray in 1898 (I assume in the USA). I think she was also married to Johnson A Rusell ( birthday: 1844; date of death: March 1918.) She had 3 children Nellie Chamberlain, Adelaide Stratton, and Emma Pearl Russell Olsen (who was born in Winnebege, Minn. August 4, 1875 and died Nov. 20, 1934. (She was my grandmother). Any information about her parents, when and where she immigrated, or information about her husband (s) would be appreciated.
