Rose Bayon is the ancestral matriarch of the Acadian Comeau family. Rose was born around 1631 presumably in France. .
Around 1649 she married Pierre Comeau. Between about 1650 and 1665 the couple had nine children: Étienne, Pierre the older called L'Esturgeon, Françoise, Jean the elder, Pierre the younger, Antoine, Jeanne, Marie-Jeanne (Marie-Anne), and Jean the younger.
In 1671 they were living in Port Royal, Acadie 
Rose died before the 1678 census as Pierre is listed as a Widower.
DNA. The Mothers of Acadia Maternal DNA project is conducting ongoing research to verify their origins. In 2010, Stephen White reported Rose Bayon had a Haplogroup J*. Ongoing test results are also reported here. As of May 2014, 1 descendant reported a J haplogroup, indicating European origins. Other tests resulted in mtDNA Haplogroup J* And a reputed descendant had mtDNA test which proved to be Haplogroup J*, not of native American origin. 
Could her father be Nicholas Bayolle? If true, evidence, not theory is needed.

It is not improbable that Barbe's father is Nicolas BAYOLLE of Dijon, who sailed beside Isaac PESSELIN on the ship "Saint-Jehan" as immigrants to Acadia, leaving La Rochelle, France on 1 Apr 1636.

Rose BAYOLS, daughter of Nicolas BAYOLS of Dijon, France [who is her mother?]. Her father had come to Acadie first in 1636 aboard the "Saint-Jehan," under the command of Nicolas LeCREUX, Lord of Breuil. He returned to France to retrieve his family and returned in 1738 with Rose. Around 1649, when she was around 18, she married at Port Royal to Pierre COMMEAU, then around 50 years of age.

It may be possible to confirm family relationships with Rose by comparing test results with other carriers of her mitochondrial DNA.
However, there are no known mtDNA test-takers in her direct maternal line.
It is likely that these autosomal DNA test-takers will share some percentage (beta) of DNA with Rose:
