The paternal relationship between James Crawford Murdock and his son
George Merrol Murdock is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant RJM.
The segmental (via DNA segment triangulation) and total DNA shared between RJM and other confirmed descendants of
John Murray Murdoch is consistent with the expected ranges for their respective relationships. Since RJM descends from John Murray Murdoch through James Crawford Murdock and his son George Merrol Murdock, the presence of significant shared DNA between RJM 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 Crawford Murdock to George Merrol Murdock, and ultimately to RJM, confirming this direct ancestral connection through multiple generations.
