The maternal relationship between Eloise Bonsaint Provost and her son Philip Joseph Vaillancourt is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant RD.

The segmental (via DNA segment triangulation) and total DNA shared between RD and other confirmed descendants of MDP is consistent with the expected ranges for their respective relationships. Since RD descends from MDP through Eloise Bonsaint Provost and her son Philip Joseph Vaillancourt, the presence of significant shared DNA between RD and other known descendants of MDP validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA MDP through Eloise Bonsaint Provost to Philip Joseph Vaillancourt, and ultimately to RD, confirming this direct ancestral connection through multiple generations.
