The paternal relationship between John Wesley Murphy and his son WDM is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant BM.

The segmental (via DNA segment triangulation) and total DNA shared between BM and other confirmed descendants of Whitson Pennington/Mary Chapman is consistent with the expected ranges for their respective relationships. Since BM descends from Whitson Pennington/Mary Chapman through John Wesley Murphy and his son WDM, the presence of significant shared DNA between BM and other known descendants of Whitson Pennington/Mary Chapman validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple Whitson Pennington/Mary Chapman through John Wesley Murphy to WDM, and ultimately to BM, confirming this direct ancestral connection through multiple generations.
