I found some census information for a Reuben Riggs in the 1850 census if anyone is interested in the details. His wife was Sarah and he had 5 children (?). One A. A. C. Riggs (age 18) is listed as being from Canada. There's also a family of Alma Riggs (43), with 8 children. These were all found in Clinton Co, Bloomfield Twp. Peggy
