JOHN A NATION, b. 1744, Virginia; d. 17 Oct 1810, Greenville County, South Carolina; m. CATHERINE ?.
From http://www.megjohn.info/genealogy/Henry_Nation_Descendants.pdf Page 5
The Vickery middle name may have crept into Gedcom data from Christopher’s will, or from aunt Elizabeth (Nation) Vickery.
Anyway, an error as far as I can tell.
