David Lennox Murdoch (13 Jan 1852 - 24 Apr 1928)

The paternal relationship between David Lennox Murdoch and his son William Murdoch is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JM.

The segmental (via DNA segment triangulation) and total DNA shared between JM and other confirmed descendants of James Murdoch/Mary Murray is consistent with the expected ranges for their respective relationships. Since JM descends from James Murdoch/Mary Murray through David Lennox Murdoch and his son William Murdoch, the presence of significant shared DNA between JM and other known descendants of James Murdoch/Mary Murray validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple James Murdoch/Mary Murray through David Lennox Murdoch to William Murdoch, and ultimately to JM, confirming this direct ancestral connection through multiple generations.
