I believe the John Absher to which you're referring was my gggrandfather John Rumsey Absher b. July 7, 1831 in Allen County Ky. and died Aug 26, 1913 in Sumner County TN. He was buried at the Mt. Olive Cemetery in Sumner County. I have photos of the stone if you like.
There were 9 sibs in all. The mother was born Mary Absher, daughter of John and Susan Barnhart Absher. There is no known record nor reason to believe that Mary was ever married. There is however an Allen County Day Court record where a man named Mitchel Smith was brought on a charge of "bastardy" for fathering John's elder brother Lytle out of wedlock namine Mary as the mother.
If I can be of further assistance, feel free to email me.
