hi my name is chris. Im a PFC. in the US Marines. I am working at a church camp for the summer called camp cho-yeh in livingston, TX. On the very back part of the property there is a texas historical cemetery. It includes the body of Capt. Isaac Newton Moreland Turner (the captain turner that you mentioned). I have somewhat good pictures of the cemetery that I took with my camera phone. There are about 9 soldiers and family buried there. It mostly consists of the Mc Caghren, Collins, and Turner family. I myself is looking up information about the soldiers buried in this cemetery that is in the middle of nowhere on the camp property. So far I have found info on capt. Isaac Newton Moreland Turner at http://usads.ms11.net/randy.html
The Sons of Confederate Veterens #1275 is what manages the cemetery. I am going back next week to take better pictures with a digital camera and can email you them if you want.
