I believe Dampier's Home Guard was from Marion County. I have a photo of a marker in the Bunker Hill Cemetery with that unit designation.
Another couple of sites to look at:
There are a couple of Confederates buried in the cemetery on the old Stringer place about a half mile southwest of the Improve Baptist Church on hwy 44.
The Burt Cemetery on hwy 98 at the Lamar County line. It's behind a locked gate.
