The maternal relationship between Jo Anne Clark and her DNA tested son JCH is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between JCH and other confirmed descendants of
David Calhoun Ratliff/
Hepzibah Illinois Waddill is consistent with the expected ranges for their respective relationships. Since JCH descends from David Calhoun Ratliff/Hepzibah Illinois Waddill through Jo Anne Clark, the presence of significant shared DNA between JCH and other known descendants of David Calhoun Ratliff/Hepzibah Illinois Waddill validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple David Calhoun Ratliff/Hepzibah Illinois Waddill through Jo Anne Clark to JCH, confirming this direct ancestral connection through multiple generations.
