I am looking for more information about Olof Larson (sometimes listed as L. O. Larson) and wife Anna (Olson). He was born Feb 1852 in Sweden, she in April 1854 in Sweden. I'm looking for when both of them died and where they might be buried. He seems to have died between 1917 and 1920 and she sometime after 1930. They lived in Garden Valley Township in Alma Center.
I'm also looking for the same information for Anna's mother Brita (Bertha) Olson. She was born Oct 1821 in Sweden and seems to have died in the 1910s. She lived in Garden Valley as well, with the family of her other daughter Greta (Gertie), who was married to G. Louis Erickson.
