Beautiful park and you might be interested in the Memphis
"Nathan Bedford Forrest Camp 215" of the Sons of Confederate Veterans.
Here is their link:

The general and his wife are buried under a large equestrian statue of the general. As the demographics of Memphis have changed some folks who have a problem with the general have tried to get the statue moved. As I understand it, the Forrest family gave the land for Forrest Park to the city for as long as the statue stayed there. If the statue and graves are moved, the property reverts to the Forrest family.
After you visit Forrest Park you need to visit the Brices Crossroads National Battlefield Site at Baldwyn, Mississippi. You probably know what happened there.
