I am trying to find an obit for Samuel White Richards, who was a church minister and was in the 1910 census in Granite Co with his wife, Amelia. His wife is buried in Douglas Co, Omaha, Nebraska and his marker says 1921, but I cannot find any cemetery info on him and cannot find an obit. Amelia passed in June of 1921.

Wondering if he died sometime between 1910 and 1920 census in Montana? Amelia is listed as widow in 1920 census and she's back in Omaha with her children.

Thanks!
