I knew I had the info somewhere (though my Denomme book is missing).
Veronique (b 24 Jan 1811 at Ste-Elisabeth, Joliette, Berthier, PQm 10 Jan 1832, same place) was the sister of my 4th great grandfather (Simon Tessier-Lavigne). Their parents were J/B Tessier and Thérèse Huppé dite LaGroix.
J/B was the son of Jacques (bap 29 Aug 1717 / d 1776) and Marie-Anne Soliquin (bap 26 Jul 1737). Thérèse was the daughter of Nicholas Huppé dit LaGroix and Marie-Catherine Miville (who is three generations from Catherine de Baillon...who you can easily look up on the Royal Connection research site through Dr. Dulong and the French-Canadian Historical Society of Michigan).
Jacques Tessier was the son of Ignace Tessier dit Avignon (son of Urbain Tessier dit Lavigne and Marie Archambault) and Marguerite Lussier (daughter of Jacques Lucier 1646/1713 and Catherine Clérice 1653/1715).
From here most everything is easily gathered from www.familysearch.org .
Now for the Charron-Ducharme line. I don't have two of the kids that you have, but I do have spouses and most marriage dates for the other five.
Élisabeth m Joseph Boucher (dite names were officially banned by then...so she chose Ducharme). Date unknown. I know they had a daughter Marie.
Julie Ducharme m Narcisse Mousseau on 15 Oct 1856 at St. Pierre, Goderich, Huron Co, ON
Joseph Ducharme m Marie Papillon on 21 Jan 1854 at St. Pierre, Goderich, Huron Co, ON
Sara Ducharme m Louis Dénommé on 28 Apr 1856 at St. Pierre, Goderich, Huron Co, ON
Arméline Charron (she did not choose to use Ducharme, which was her perogative when the Brits did away with dite names in Canada) m Évangeliste Brisson on 7 Feb 1860 at St. Pierre, Goderich, Huron Co, ON.
Now Jean-Baptiste Charron dit Ducharme was b. 28 Feb 1814 at Ste-Elisabeth, Joliette, Berthier, PQ. He was the son of Joseph Charron dit Ducharme (bap 1789) and Marie-Anne Carpentier (b 1792) who were married 5 Aug 1811. He was also the brother of my 3rd great grandmother...so I guess we're double cousins :-)
Joseph was the son of Joseph (b 1767/d bef 1811) and Catherine Geoffroi (m 1788) Marie-Anne was the daughter of Jacques and Genevieve Savignac
Joseph the father was the son of J/B and Genevieve Joly Catherine was the daughter of Jean-François Geoffroi and Marie-Amable LaPorte Jacques Carpentier was the son of Pierre and Marie Aide dite Creque. I can take Marie's line back to Jean Guyon (b. abt 1500). But there's not enough room for that here.
The Ducharme/Charron Association is extremely well organized and can get you all sorts of info on this family. What I can tell you is that you're related to a good number of famous French Canadians, including Celine Dion, the Dionne quintuplets (8 different ways at least) and former Prime Minister Pierre Trudeau. The Catherine de Baillon line has been traced back to Charlemagne and well documented.
If you're related to any of the Bedard's from the Thumb area of Michigan, I can also give you that line. Just let me know how far you go back. If you go back through Henry Badour (fka Henri Andre Bedard), then I have your entire tree, as he married on of my gg-grandaunts. The Denomme line is extremely well documented and you shouldn't have any problems getting that info.
If you need anything, don't hesitate to drop me a note. Happy hunting...and welcome to the family.
