This couple's marriage record is part of the Drouin Collection on
www.ancestry.com.
My French is very poor. I believe they were married on August 30, 1864 at L'Isle Verte (St-Jean-Baptiste) in Riviere-de-Loup County.
David Beaulieu's parents were Jean Baptiste Beaulieu and Genevieve Paradis.
Angele Soucy's parents were Thomas Soucy and
Appoline Grand Maison.
Note: Thomas and Appoline's marriage record is also posted.
They were married February 16, 1841 in Cacouna. Thomas' parents were Jean Baptist Soucy and Genevieve Belanger.
Appoline Grand Maison's parents were, I think, Alvin Grand Maison and Modiste Mapuis.
I did not look up any other records. If you do not have access to ancestry.com's world or Canadian collections than I suggest you check you local library to see if they have a free access to ancestry.com You will want to look at these orginial documents and you may be able to take the direct line back even further.
Good luck,
