Oluf H. Pederson, b 18 June 1864 in Huckelhustuen, Birid, Oppland, Norway (father - Peder Arneson Huskelhus - mother - Sessel Jergensdatter) was my great grandfather. He married Caroline Kjerstine Simonson.....(she was born 02 Oct 1867 in Minnesota, USA). I am requesting help in locating this mans emigration date and location. thank you, Bev Porter Moltzau
