The paternal relationship between Harold Robert Merrill and his son RDM is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant RDM.

The segmental (via DNA segment triangulation) and total DNA shared between RDM and other confirmed descendants of George Edwin Merrill/Catherine Hummell is consistent with the expected ranges for their respective relationships. Since RDM descends from George Edwin Merrill/Catherine Hummell through Harold Robert Merrill and his son RDM, the presence of significant shared DNA between RDM and other known descendants of George Edwin Merrill/Catherine Hummell validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple George Edwin Merrill/Catherine Hummell through Harold Robert Merrill to RDM, and ultimately to RDM, confirming this direct ancestral connection through multiple generations.
