Sorry I don't know about the Powell's but, my Durham's are from Casey Co., Durham Ridge. How far back have You been able to go? I was told once that all Durham in that area of Ky. are related. Mine go back to a Thomas Durham of Mercer Co.,Ky. A son David Milton, or Melton David was in Casey Co. on 1810 Census. Any info appreciated.
