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