To answer your question about this particular Augustin Paquin married to Genevieve Pivard married in 1909, you have, I believe, the wrong name for the spouse. I have an Augustin Paquin married to a Genevieve Rivard dit Lacoursiere on February 10, 1809 at St Pierre les becquets PQ Canada. They had 15 children and only one marriage took place.
I have this family on computer back to France as well as all the children's marriages etc. If you want more info please contact me atReginald.Paquin@Verizon.Net
