Lars and Louis are two different people, I do not know which is correct!
Lars Larson was married to Gundine, he was a baker.
Louis H. Larson was married to Lena Taraldson. Louis
had a grocers store.
Nels H. Larson married Lena Hanson 11 Feb 1899 in Washburn
Ole H. Larson married Anna Aschim 31 Oct 1896 in Washburn
Maybe Louis H. Larson is correct. What is the "H" for?
