Hello, I have been focusing on this person and related families in the "Clan Henderson Family Group R-K1: BY42705" Project (found here: https://www.geni.com/projects/Clan-Henderson-Family-Group-R-K1-BY42... ).
This group shows a close genetic match, within the last 300-400 years, of all 5 included DNA kits. Solid documentation and thorough research lead me to the conclusion that James Henderson who died c. 1807-1812 in Clermont County, Ohio is James Henderson from Greenbrier Co., VA (now WV). He is not, however, the James Henderson proposed here as being from Augusta County, Virginia, with the ancestry previously documented for that family.
For the time being, I propose splitting this person between the Augusta County, VA, and the Greenbrier County, VA(WV) linkages. Thoughts?
