My g-grandmother was Helen Thompson b. 1894 WY. Her father was Charles Christen Thompson b. Dec 14 1863 Denmark.
He appears to have immigrated in 1881 or 82, married Effie Waite in Montana in 1889, and had daughters Helen and Mabel. Effie died in 1908, and in 1910 he remarried to Ellen Christensesn (born of Norwegian parents in Iowa).
Charles died Jan 24 1935 in Spearfish SD.
A couple of records have him listed as German, but with Danish parents, though several others have him born in Denmark. Several of his childrens' records show them as Dane rather than German as well.
Near as I can tell he only had the 2 daughters so his name line would have ended. Helen's children were Bolson, Mabel's were Bonefield.
Does anybody have suggestions to finding Charles' parentage & possible siblings?
