"The Guyon Dilemma"
As most of us know who have been at Chiasson genealogy for any length of time, it had been generally accepted for quite some time, that Guyon likely had three marriages. Beyond that however, there were many conflicting theories about how that actually worked out in terms of his family.
We always knew for sure that Guyon had married Jeanne Bernard in 1666 at Port Royal, and Marie-Madeleine Martin in 1683 at Quebec, returning after that to live at Beaubassin.
Those who believed he had a third marriage seemed divided as to the date of the third marriage but all were in agreement that his third wife would have been Marie Beliveau. Some had her being married to Guyon in 1664 (before the Bernard marriage). Some said it was about 1680 (between the Bernard and Martin marriages). There has always been confusion as to exactly which children belonged to which mother.
As time went by, with now being able to prove that Anne (dit Lavallee) (1680) was indeed the daughter of Jeanne Bernard, and given that Guyon had gone to Quebec after Jeanne Bernard's death, and the Martin marriage was in 1683, it seemed more and more that if Guyon had been married to Beliveau, it would have had to be at the earlier date.
Then the long awaited Dictionnaire Généalogique des Familles Acadiennes by Stephen White, which had been in the making since 1978 or earlier, was finally published in the mid 90's. It took far more than 20 years to compile because the objective was to make it as complete and as accurate as possible, and odd bits of data kept surfacing. Once the Dictionnaire finally arrived, it was regarded as the most reliable and accurate publication of its kind to date. And it still is.
But Stephen White's data challenged the previously accepted theory of Guyon having had three marriages. And he very clearly proved the case. He also adjusted some dates of birth for Guyon's children and clarified some confusion about two children appearing to have different names in some collections of data.
And now, with new information just in, (29 Jan 2003) (see the notes at the bottom of Guyon's page), there is even more proof that such a third marriage is simply not believable.
Some of us were quick to jump on the new data and correct our pages. Unfortunately though, there are still unfathomable numbers of pages and archives out there, online and otherwise, that still have the old data, and to our dismay, likely always will. At least once a week, someone e-mails me about this.
To some of us, it may seem insignificant, especially if we are more interested in more recent generations. But for those of us who are trying to build reliable databases from the ground up, this "Guyon dillemma" promises to be a very controversial subject and the source of much confusion for a very long time to come.
