Do you by any chance have the father’s name of your Joseph Isenhour?
You may also want to check the research entries from Jimmie Woolbright and Ben Callahan. You will find then in the RootsWeb Isenhour listings. Their data covers a much wider area than does mine. My direct line is from Hans Nicholas and Anna Margaretha (nee: Struble) Eisenhouer from around 1690-1700, from Germany. In the intervening years a number of limbs have split off the main trunk and several of the branches are in the Mid Carolina areas.
Researching: Howell, Ray, Isenhour, Howard, Myers, Shumate, Massey, Boger, et at.
I will gladly exchange genealogy information.
