The maternal relationship between Nancy Annie Roberts and her daughter
Sarah Burkhart is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant KS.
The segmental (via DNA segment triangulation) and total DNA shared between KS and other confirmed descendants of JJR/D is consistent with the expected ranges for their respective relationships. Since KS descends from JJR/D through Nancy Annie Roberts and her daughter Sarah Burkhart, the presence of significant shared DNA between KS and other known descendants of JJR/D validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple JJR/D through Nancy Annie Roberts to Sarah Burkhart, and ultimately to KS, confirming this direct ancestral connection through multiple generations.
