Jack, A year later you proablly have the answer by now. Search Jefferson and Fayette county court records for wills and deeds. If this is oral history you will have to prove it. If he freed him just before the war ended the record is at the courthouse. He would have to carry the papers.

What is interesting to me is that if he was free why the need for the underground railroad. Would love to hear what you have found out. I'm not related just interested.
