I am researching the family of Robert William Clark, my great grandfather, who was Chief Factory Inspector for the S.A. govt. in the early 20th century. His offspring included:Emily Olivia 1883-1909,Thomas Hutchinson 1885-1918 (my grandfather),Herbert Hinde 1888-1960,Ada Clarice 1890-1962,William Clarence 1893-1947. Their offspring were:Robert William Clark 1920-?,Clarice Lucy 1925-?,Joan Mary 1918-?,and Margret 1921-? Any data on their offspring would help me construct my fam. tree.
