The evidence presented by these researchers is certainly tantalizing, even compelling, but as noted there is still a missing link to connect the Andrée Guyon and Charles Bernard the sailor of France with Andrée Guyon and ? Bernard of Acadia [assuming ? was ever in Acadia]. We need to make this crystal clear that it is a hypothesis, not a fact, that these two couples are the same. It also needs to be made clear that the first two supposed children, Guillaume and Dominique, are hypothetical and not proven for the Acadian couple. As it stands, the profile for Charles is entirely based on this hypothesis, but gives no hint of it until the last paragraph in the research notes, which might easily be overlooked by a casual reader.
I would suggest reorganizing the narrative somewhat, to begin with what is known about them from Acadian records, and only then to present the evidence for a possible link to a couple with similar names in France. There should be no doubt after reading the biography that these connections are not proven.
I also think citations with direct links to the records should be included, in addition to the analyses by the other researchers. That may seem redundant, but it's necessary for good genealogical reporting, and to ensure that we don't lose track of the records in the future. You never know when a site will disappear or move.
That's my two bits. Hope it helps!
