Thanks for the reply. I was the one who made the original post. There is a memorial on the Find-A-Grave site for him. It is Find A Grave Memorial# 38154708 (http://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GSln=warren&GSiman=1&GScid=32854&GRid=38154708&) in case you are interested. The memorial has a photo of the grave and marker, though it is a little hard to read. It's the only Warren grave listed in the cemetery. I don't have any idea how he came to be in Thomas County.
Thanks for your help.
