In the late 1700s or the early 1800s and to this day there have been Mayfields in Monroe County, MS. I used to correspond with Gracie Mayfield Morlina who knew so much about the area and my family. Gracie has been gone for a few years now, but I see that there are currently Mayfields in Monroe and Lowndes Counties. You might try the Mayfield surname in these boards or even the telephone book for surrounding counties. I have had some good responses doing that.
My family names who had land, some possibly plantations in Monroe and surrounding counties are Sims, Brown, Phillips, Cocke, Walker, Holloway, McClendon, Owens, Murrell...more. If you recognize any of these names, I would surely appreciate a reply.
