I would like to know if anyone has any information on Andrew Olson Krogstad Born in Norway on June 27, 1858 and Petra Olson born on Dec. 29,1868 in Norway. When Andrew came to the U.S. he changed his name to Krogstad because there were so many Olsons over here. They were married in the U.S. Please let me know of any information you may have. Does anyone have any information on their ancestors of siblings?
