The maternal relationship between Helen Marjorie Rivard and her DNA tested daughter LAD is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between LAD and other confirmed descendants of
Joseph Marie Saucier/
Marie-Genevieve Tremblay is consistent with the expected ranges for their respective relationships. Since LAD descends from Joseph Marie Saucier/Marie-Genevieve Tremblay through Helen Marjorie Rivard, the presence of significant shared DNA between LAD 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 Helen Marjorie Rivard to LAD, confirming this direct ancestral connection through multiple generations.
