The Blair Cemetery is located at N33 deg 51.593 min and W88 deg 16.994 min.
It is not generally known but the Blair Cemetery in Monroe, Co. MS had a section where freed slaves and their children are buried. My Great-grandfather Curtis Hardy Wise owned slaves and some of the interred bear our family name.
The only other information I can provide is that my Aunt Mommie Wise (born 1892) said that two of the freed slaves moved away when they married. One was Laura, who married Frank Hollis and the other was West Wise. Frank Hollis is probably related to the F. H. & L. J. Hollis mentioned on the stone of Lowell P. Hollis.
Also, the Sullivan Cemetery has an African section. Unfortunately, county workers bulldozed the markers away many years ago. As I recall some of their birth dates were in the mid-1700s. Hopefully, some of the stones may be recoverable and I intend to look next winter. The Sullivan Cemetery had the oldest marked grave in the country, a burial in 1822. That cemetery is located at N33 deg 46.378 min & W88 deg 18.134 min.
