There are some Mississippi soldiers buried at Camp Beauregard near Water Valley, KY. The camp is a bit difficult to find. It's on the east side of highway 45. There is an old DCV marker at the turn-off of 45. It's maybe three to five miles once you turn. There is a memorial at the site.
I seem to remember the remains of some of the Miss soldiers were moved to Miss years after the war ended.
Good hunting.
