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
Pierre Patenaude/
Catherine Brunet dit Belhumeur is consistent with the expected ranges for their respective relationships. Since KLF descends from Pierre Patenaude/Catherine Brunet dit Belhumeur through Felicite Prairie and her daughter Florence O'Brien, the presence of significant shared DNA between KLF and other known descendants of Pierre Patenaude/Catherine Brunet dit Belhumeur validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Pierre Patenaude/Catherine Brunet dit Belhumeur through Felicite Prairie to Florence O'Brien, and ultimately to KLF, confirming this direct ancestral connection through multiple generations.
