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