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