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