I have found the listing of my great grandmother on the 1885 Minnesota census for Otter Tail County (Nina Christine Torgerson, b. abt 1875). I am having trouble finding information on her parents, Ole Torgerson and Kari (Carrie). From the 1885 and 1890 census, it appears Nina's other siblings were Sarah, Martin, Teandor, martin, John, Olaus, Ingeborg (Julia). Is there anyone out there who might be researching sibling information who can direct me further on the parents' history?
