Anton Olson b. 1883 Gausdal Norway

I need assistance researching my great grandfather, Anton Olson. I’m looking for documentation of basic genealogical information about his parents, siblings, etc. and I’m hoping to learn which farm he lived on, who owned it, etc. Here’s what I’ve been able to scrape together so far through oral history and unofficial sources: Name: Anton Olson Birthdate: 26-January 1883 Birthplace: a farm in Gausdal Norway Parents: Ole Olson and Caroline Olson Brother: Christ (emigrated to America - North Dakota) Sister: Karen, Mrs. Ole Hovslakken, Lillihammer Uncles: Fred and Anton Peterson (emigrated to America - North Dakota sometime before 1906) Arrival in United States: 1906 (settled near Litchville ND) Spouse: Bertha Marie (married 06-July 1913 in Minneapolis MN) Death: May-1974, Valley City ND I’d appreciate whatever help anyone here can provide. Thanks so much!
