Can anyone offer an advice to the following problem I have? My great-grandfather moved his family to Sharon, Mercer County around 1906 and he and his wife died there in 1928 and 1941, respectively. However, I cannot find either of them on the 1910, 1920, and 1930 census. I find their (married) children but not them. Their obituaries state that they were longtime residents of Sharon. Does anyone have any ideas why I can't find them in any Mercer County censuses? WILSON, David b. 1854 Ohio WILSON, Eliza b. 1857 Ohio Thanks, Rick Wilson rwilson7@aol.com St. Louis, MO
