Good question! I cleaned the profile and reorganized so that it is easier to follow. However the two sources cited are shaky in that one is secondary and the relationship of Peter Peter as being the correct Pierre Pitre is not firm. The second one is a marriage record of the son, which looks original except that Martine Gallant as mother was clearly added later.
If you have better/different information, please add a section on research notes or add it as a comment to the profile. Source links would be most helpful.
