The paternal relationship between Jean Baptiste Brault and his son
Pierre David Brault 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 Jean Baptiste Brault and his son Pierre David Brault, the presence of significant shared DNA between KLF and other known descendants of Alexis Brault/Marguerite Barriault validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple Alexis Brault/Marguerite Barriault through Jean Baptiste Brault to Pierre David Brault, and ultimately to KLF, confirming this direct ancestral connection through multiple generations.
