I have civil war veteran William Adams, b. 1844 July 10 in Norway, living in 1870 on the census with wife and kids and his father and mother in Minnesota, Adam Albertson and Gunild. Adam born ca. 1815.
Both men (father and son) homesteaded in Douglas County, Orange township, and were naturalized in Douglas county, but those records don't give any place in Norway.
It is obvious that William has Americanized his name. One record says William Anton Adams.
The family emigrated about 1861 from Norway, but obviously there was a name change.
William Adams and wife Caroline (Nelson?) Adams died in Benton County, Minnesota.
Gunild and Adam Albertson supposedly died in Douglas county, Minnesota, she in the 1870's and he about 1880, but I can find no record of their deaths in Douglas county.
Other possible family members of Adam Albertson and Gunild are the children
