The maternal relationship between Adelina Vigeant and her daughter
Yvonne Vigneault is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant DT.
The segmental (via DNA segment triangulation) and total DNA shared between DT and other confirmed descendants of
Alexis Brault/
Marguerite Barriault is consistent with the expected ranges for their respective relationships. Since DT descends from Alexis Brault/Marguerite Barriault through Adelina Vigeant and her daughter Yvonne Vigneault, the presence of significant shared DNA between DT and other known descendants of Alexis Brault/Marguerite Barriault validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Alexis Brault/Marguerite Barriault through Adelina Vigeant to Yvonne Vigneault, and ultimately to DT, confirming this direct ancestral connection through multiple generations.
