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