I have found a Francois Bertrand in my Family Tree, 3rd great grandfather.
I cannot confirm if it is the "same" Francois, but here is my connection as follows:
Francois Bertrand: (3rd Great), married to Angelique St. Bernard
Richard Bertrand: (2nd Great), son of Francois and Angelique, Married to Reine LaForge
Matilda Bertrand: (Great), daughter of Richard and Reine, married to Joseph Dennis
John Dennis: (Grandfather), son of Joseph and Matilda, married to Muriel Mullins
John Calvin Dennis: My father
Thank you for amny help you might have.
