According to obit. on Mansfield Dunning,he came to the Black Hills of SD. in the spring of 1879. He was married to Huldah Helen West in Knox Co.,Ill in 1856 and then moved to Iowa. If anyone has access to a 1880 census,would you please look for Mansfield O. Dunning,with wife Huldah. Children's names that I know are:'William Charles,Luther J.,Etta,Nellie and Marybelle. Thank you. Rebecca R. Sisk
