William Gracey, born in Northern Ireland settled in White Co., Tn. He had a son John Gracey who moved to Mississippi. I didn't see a reference to the exact location in Mississippi which John Gracey moved to, but it is known that he moved his family to MS. John was born in Ireland.
The names of John's children which you posted are names of this Gracey Family. The name Amanda and Waymon are common, especially Wayman.
I am not a Gracey descendant, but my grandfather's first wife was Amanda Gracey. See my followup for Linda Murphy on Gracey Home Page.
