The maternal relationship between Mary Frances Wilson and her son Roy Lee Sayers is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MTB.

The segmental (via DNA segment triangulation) and total DNA shared between MTB and other confirmed descendants of Daniel Wilson/Sarah Ann Combs is consistent with the expected ranges for their respective relationships. Since MTB descends from Daniel Wilson/Sarah Ann Combs through Mary Frances Wilson and her son Roy Lee Sayers, the presence of significant shared DNA between MTB and other known descendants of Daniel Wilson/Sarah Ann Combs validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Daniel Wilson/Sarah Ann Combs through Mary Frances Wilson to Roy Lee Sayers, and ultimately to MTB, confirming this direct ancestral connection through multiple generations.
