The paternal relationship between Francis Marion Hatcher and his son
Andrew Jackson "jack" Hatcher is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant AH.
The segmental (via DNA segment triangulation) and total DNA shared between AH and other confirmed descendants of
James Fulton Hatcher/
Catherine Elizabeth Martin is consistent with the expected ranges for their respective relationships. Since AH descends from James Fulton Hatcher/Catherine Elizabeth Martin through Francis Marion Hatcher and his son Andrew Jackson "jack" Hatcher, the presence of significant shared DNA between AH and other known descendants of James Fulton Hatcher/Catherine Elizabeth Martin validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple James Fulton Hatcher/Catherine Elizabeth Martin through Francis Marion Hatcher to Andrew Jackson "jack" Hatcher, and ultimately to AH, confirming this direct ancestral connection through multiple generations.
