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