I would like to determine the father of my grandfather, Nels Anderson. That was the name he went by here in Minnesota. His mother we know as Gunvor Endresdatter Thorstad, born 1820 in Svien, Wangs, Oppland. Nels has a give birthdate of about 1850. We believe he was illegitimate and was born in Norway. His mother emigrated in 1864 as the wife of Knut Reierson Lie. The name of the father may or may not be Anders Bjornson. Any help that anyone could give in the matter would be very greatly appreciated. You can reply off-list if you wish. Be
