The maternal relationship between Mary Genevieve Black and her DNA tested son DLW is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between DLW and other confirmed descendants of
Zadock Barnard/
Mary Short is consistent with the expected ranges for their respective relationships. Since DLW descends from Zadock Barnard/Mary Short through Mary Genevieve Black, the presence of significant shared DNA between DLW and other known descendants of Zadock Barnard/Mary Short validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Zadock Barnard/Mary Short through Mary Genevieve Black to DLW, confirming this direct ancestral connection through multiple generations.
