The maternal relationship between Susanne Rivard dit Lavigne and her son
Joseph Pomerville is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant DD.
The segmental (via DNA segment triangulation) and total DNA shared between DD and other confirmed descendants of
Joseph Marie Saucier/
Marie-Genevieve Tremblay is consistent with the expected ranges for their respective relationships. Since DD descends from Joseph Marie Saucier/Marie-Genevieve Tremblay through Susanne Rivard dit Lavigne and her son Joseph Pomerville, the presence of significant shared DNA between DD and other known descendants of Joseph Marie Saucier/Marie-Genevieve Tremblay validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Joseph Marie Saucier/Marie-Genevieve Tremblay through Susanne Rivard dit Lavigne to Joseph Pomerville, and ultimately to DD, confirming this direct ancestral connection through multiple generations.
