The proposed relationship of Marguerite Barriault as the mother of
Jean Baptiste Brault,
Francoise Rose Brault and
Anne Josephe Brault is supported by DNA evidence indicating shared ancestry within the family lines.
Specifically, DNA evidence confirms a distant cousin relationship between DT (a descendant of the Francoise Rose Brault ancestral line) and KLF (a descendant of the Jean Baptiste Brault ancestral line) with 14.21 cM of shared DNA across 1 HIR segments.
It also confirms a distant cousin relationship between DT (a descendant of the Francoise Rose Brault ancestral line) and CW (a descendant of the Anne Josephe Brault ancestral line) with 57.47 cM of shared DNA across 3 HIR segments.
These matches are consistent with their placement within these shared ancestral branches.
