Jon, I was very much interested in your commentary on the Old Slave House. Thank you for your clarity explaining what this hot topic was all about. Also for your historical information that you frequently contribute. I am wondering about the John Duff you mentioned. Was he perhaps related to the Hiram Duff from Sumner Co TN? Hiram Duff married Frances Dugger and they moved to Gallatin Co. about 1830. They had a son named John. Carol Dugger
