The paternal relationship between David Murdock Stewart and his DNA tested daughter BLS is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between BLS and other confirmed descendants of
John Murray Murdoch/
Ann Steele is consistent with the expected ranges for their respective relationships. Since BLS descends from John Murray Murdoch/Ann Steele through David Murdock Stewart, the presence of significant shared DNA between BLS 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 David Murdock Stewart to BLS, confirming this direct ancestral connection through multiple generations.
