N. Brown,
I was looking up some info on him because I hadd always heard I was related. The only thing I found to add to your great family tree info is that John and wife Jane Bowen had, as I found, 4 children: Mary Elizabeth, John Wesley Hardin III, Callie Hardin, and Jane Martina Hardin (7.15.1877 in Alabame and died 10.12.1931 in Texas) Her spouse was John Ross Lyons. The info I found said Callie Hardin's spouse was Jon Lyons.
