I say that we are all descendants of Robert de La Berge because there was only one Laberge who came to La Nouvelle France (New France - now the Province of Quebec, Canada).
While there is always a possibility that other Laberge(s)/de La Berge(s) came later, most Laberge, La Berge, Labarge, and La Barge are indeed descendants of said Robert de La Berge. So, if you post a message on the Laberge GenForum you might find someone who can help... might even be myself.
An effective posting needs the following: Groom's name (such as Guillaume Laberge) Date married (whatever date and place) Bride's maiden name (such as Barbe Julien)
Also enclose any bit of information you might have. So... if your gr-gr-grandfather was Alfred Augustus La Barge, who was your gr-gr-grandmother? Remember we need her maiden name. If you don't have your gr-gr-grandmother's name please post your gr-grandparents' names, date/place where they were married. Hopefully someone will have something for you.
And here is a bit of history on Robert de La Berge: Born May 24, 1638 in Colomby-sur-Thaon, Calvados, Normandie, France. Godparents were Charles de La Berge & Cardine Faillaize. He arrived in New France on August 6, 1658 aboard the vessel "Le Taureau" (The Taurus). On May 28, 1663 in Château-Richer, Quebec, Canada, he married Françoise Gausse dit Le Borgne, born 1634 in St-Martin-de-Noyon, Normandie, France. They had 3 daughters: Geneviève, Françoise, and Catherine. and they had 3 sons: François, Nicolas, and Guillaume.
I hope this bit of information is enough to make you want to know even more on your ancestors. Hope to read you soon again!
