Mr. Clifford,
Are you working with Mr. Dewey DeLee on this project? Or is it something of you own? I believe Mr. Dewey has a pretty lengthy list. Also, Ms. Eva Francis Phares may have a good deal of information on the cemetery. Both are local to Clinton. If you are already in contact with them, I am sorry for troubling you with information you might already have.

On a side note, where are you planning on placing the stones? I don't remember enough room in the lower part of the cemetery for near about that many. I believe the road below the cemetery amd apartment complex (not what I would call it, but I'm being nice) is covering alot of graves. Is this true? What about the football/track field? Is it on part of the old cemetery?
Sorry your question to us, has turned into many from me to you. I am located in Liberty, MS, and would love to chat with you sometime on the cemetery. If you would, email me at virgilroberts@hotmail.com and maybe we can arrange a meeting.

Virgil
(PS, would love to own Marston, and restore it! beautiful place!)
