Paule, Are you still researching Pierre Vezina and Celina Charette? If so, have you determined that Pierre Vezina is your direct ancestor? And, if so, have you considered yDNA testing? If you are directly descended, you may be able to determine if Pierre was indeed a Vezina by testing against other Vezina's, possibly at familytreedna.com. Otherwise it seems our Pierre was a foundling and possible adopted by a Vezina family -- see my conversations with Winfrid Grimard regarding this subject.
