I have been looking for a John Young that was supposed to have died in Clarksville, Illinois in 1834. I can't find Clarkville, Illinois---was just wondering could it have been Clarksville, TN instead? Can anyone tell me where Clarksville, TN is located. I can't find it on my maps. I live in S. Texas and have no idea where any of these Clarksvilles are located. Thanks for your help. Dot P.
