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