Only one Mayfield (Abraham) is shown in the 1790 census for York County, South Carolina.  However, there is no mention of this person in the official records for York.  The following Deed Book entry is the only one noted involving anyone with the Mayfield surname during the time frame from 1785 to 1868. 

30 October 1783:  William Mayfield conveys to Elizabeth Meek, for $540, a 283-acre tract of land in York County adjacent to the "Hambrick Line."  The geographic location of the "Hambrick Line" is not known by me.  The indenture was witnessed by Thomas Weir and Milton Jamison.  William Mayfield signs by making his mark.  Deed was recorded on 19 May 1826.  [See York County SC Deed book K, page 412]
