The paternal relationship between Curtis Grove Ratliff and his daughter Mary Magdalene Ratliff 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 Curtis Grove Ratliff and his daughter Mary Magdalene Ratliff, 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 paternal line.

This supports the conclusion that DNA was passed from MRCA couple David Calhoun Ratliff/Hepzibah Illinois Waddill through Curtis Grove Ratliff to Mary Magdalene Ratliff, and ultimately to PS, confirming this direct ancestral connection through multiple generations.
