The maternal relationship between Helena Marie Ayo and her daughter
Mildred Isabel Landry is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant CW.
The segmental (via DNA segment triangulation) and total DNA shared between CW and other confirmed descendants of
Alexis Brault/
Marguerite Barriault is consistent with the expected ranges for their respective relationships. Since CW descends from Alexis Brault/Marguerite Barriault through Helena Marie Ayo and her daughter Mildred Isabel Landry, the presence of significant shared DNA between CW 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 Helena Marie Ayo to Mildred Isabel Landry, and ultimately to CW, confirming this direct ancestral connection through multiple generations.
