Does anyone have an index to the Polk Co Census of 1870, 1880, 1900 I am trying to find Richard Whiteside who married Sarah Walker Edgerton. I am interested in finding their 10th child, Louisa Ella Whiteside who was born in 1865. The family might have lived in the Poplar Grove area. Louisa might be listed in the 1900 census as the wife of Otis Columbus Cochran. Thanks for your time. Ann
