Am I related to Roald Amundsen

My mother told me that we were related to Roald Amundsen but I am not sure how? Can you help me confirm, please? My Mother's maiden name was Doris Solem and she grew up in North Dakota and born in Arnegard, North Dakota 04/17/1916. My mother said we were related through her mother Anna Larson who was born in Iowa. Anna Larson died in North Dakota when my Mother was only 16 years old so Anna Larson would have died around 1932 or so. I don't have any details but I believe Anna Larson was related to someone named Eriksen who then was related to Roald Amundsen. I am sorry I don't have more details, but would love to know if I am in fact related to this famous Norwegian explorer.
