The maternal relationship between Aritha Deanne Lloyd and her daughter SDB is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant DO.
The segmental (via DNA segment triangulation) and total DNA shared between DO and other confirmed descendants of
John Murray Murdoch/
Ann Steele is consistent with the expected ranges for their respective relationships. Since DO descends from John Murray Murdoch/Ann Steele through Aritha Deanne Lloyd and her daughter SDB, the presence of significant shared DNA between DO 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 Aritha Deanne Lloyd to SDB, and ultimately to DO, confirming this direct ancestral connection through multiple generations.
