The paternal relationship between Ennis Russell Pennington and his son MYP is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant PDP.

The segmental (via DNA segment triangulation) and total DNA shared between PDP and other confirmed descendants of Isaac Newton Pennington/Nancy Ann Johndrow is consistent with the expected ranges for their respective relationships. Since PDP descends from Isaac Newton Pennington/Nancy Ann Johndrow through Ennis Russell Pennington and his son MYP, the presence of significant shared DNA between PDP and other known descendants of Isaac Newton Pennington/Nancy Ann Johndrow validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple Isaac Newton Pennington/Nancy Ann Johndrow through Ennis Russell Pennington to MYP, and ultimately to PDP, confirming this direct ancestral connection through multiple generations.
