The maternal relationship between Bertha Belle Trombly and her son
Coriel Trombly is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant DT.
The segmental (via DNA segment triangulation) and total DNA shared between DT and other confirmed descendants of
Jean Louis Patenaude/
Genevieve Lareau is consistent with the expected ranges for their respective relationships. Since DT descends from Jean Louis Patenaude/Genevieve Lareau through Bertha Belle Trombly and her son Coriel Trombly, the presence of significant shared DNA between DT and other known descendants of Jean Louis Patenaude/Genevieve Lareau validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Jean Louis Patenaude/Genevieve Lareau through Bertha Belle Trombly to Coriel Trombly, and ultimately to DT, confirming this direct ancestral connection through multiple generations.
