The maternal relationship between Mary Magdalene Ratliff and her son CTS is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant PS.
The segmental (via DNA segment triangulation) and total DNA shared between PS and other confirmed descendants of
David Calhoun Ratliff/
Hepzibah Illinois Waddill is consistent with the expected ranges for their respective relationships. Since PS descends from David Calhoun Ratliff/Hepzibah Illinois Waddill through Mary Magdalene Ratliff and her son CTS, the presence of significant shared DNA between PS 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 Mary Magdalene Ratliff to CTS, and ultimately to PS, confirming this direct ancestral connection through multiple generations.
