The maternal relationship between Mary Polly Hartman and her daughter
Barbara Ann Burkett is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant CRB.
The segmental (via DNA segment triangulation) and total DNA shared between CRB and other confirmed descendants of
Abraham Hartman is consistent with the expected ranges for their respective relationships. Since CRB descends from Abraham Hartman through Mary Polly Hartman and her daughter Barbara Ann Burkett, the presence of significant shared DNA between CRB and other known descendants of Abraham Hartman validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA Abraham Hartman through Mary Polly Hartman to Barbara Ann Burkett, and ultimately to CRB, confirming this direct ancestral connection through multiple generations.
