I am searching for more information re: Andrew and Karl Schmutz who I found in Lewellyn Park township in Sully County, SD in the 1920 US census. They immigrated from Baden, Germany about 1880-1882. I believe they may be the lost foster brothers of my grandfather Frank Xavier Schneider who lived in St. Paul, MN. The story is he had a dispute with his brothers (foster) who left for South Dakota. Any information or suggestions would be greatly appreciated.
