Sue, You did not write to me but I am a lurker I guess you would call it. There was a Samuel Riddle in McMinn, Co. Tn. and I believe they told me he was the only one that owned land in that county with the name Riddle. I was trying to locate some information on my Benjamin and Francis Riddle. So you may be able to check there and it may not be your Samuel anyway. That was in the 1800's. Sorry cannot give you a specific date. I really do not think they look without you being there any way. We later have been there three times so I know I found where my Benjamin had owned land. wrak
