Thanks to a FindAGrave contributor, I now have a photograph of the tombstone of my paternal step-2nd great-grandfather, Robert E. Kimble (1841-1918). Robert is buried in the Spring Hill Cemetery, Fort Recovery, Mercer County, Ohio.
This marker shows Robert and his first wife, Catherine. Robert married secondly to my widowed 2nd-great grandmother, Mary Jane (Sherrick) Haley on May 8, 1897 in Jay County, Indiana.
This record clears up some confusion as to whether or not his middle initial was 'N.' or 'E.'. Handwriting and other records made it hard to decipher.
It appears that Robert and Catherine's son, John Wesley Kimble is buried in the same cemetery.
