I am trying to find any info on my great grandmother and her family. She is Mary Oletti Otterbeck who was born in Norway and came to America with her family. Her siblings were Matilda, Christina and Andrew Otterbeck. They came to America with their mother and stepfather--Ann and Anthon Skanchy. Mary married Peter Christensen in Utah. I am trying to go back farther on the Otterbeck family in Norway. The children's biological father was a sea captain in Norway and went down with his ship. Any help would be very much appreciated.
