George:
Here are links to two pages I know of that list a number of Confederate burials in Rutherford County, including Murfreesboro. The first a list of men know to be buried in the Confederate Circle in Evergreen Cemetery. Unfortunately this short list are all the men known out of more than 2,000 beuried there. The other link is from a survey of Rutherford County cemeteries.
There are a few Mississippi men in these lists.
YOS,
