Jenny Amalie Jansen

I am searching Jenny Amalie Jansen born Jørstad in Strømsø Drammen Norway 22. Mars 1858. I have fond that she in 1885 visited her father Christinan Larsen Jørstad in Drammen Norway at Christmas 1885. (Norway Census http://digitalarkivet.arkivverket.no/ft/person/pf01053263013499). Then she had her douther Eva Sophie born the same year 1885 with her. I belive she lived in USA but are not sure about that. I have not found her marrige in Norway so I don't know the name of her husbond otherwise his family name is Jansen and are born in Norway? Can have schanged the spelling in USA ex. Janson Hope someone kan find something about her. Ske was a aunt of my mother. Hopfully TOK
