The paternal relationship between James Howard Murdoch and his DNA tested son RM is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between RM and other confirmed descendants of
John Murray Murdoch is consistent with the expected ranges for their respective relationships. Since RM descends from John Murray Murdoch through James Howard Murdoch, the presence of significant shared DNA between RM and other known descendants of John Murray Murdoch validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA John Murray Murdoch through James Howard Murdoch to RM, confirming this direct ancestral connection through multiple generations.
