Boujour Ernest, Hello!
In the Marriage Register of the Parish of St-Joachim ~ 1736-1963, Châteauguay, Québec, I found the following:
DESGROSEILLERS, François (Frs & Louise Roi)
Married: October 19, 1829 in Châteauguay, QC
LEMIEUX, Jovite (Jn-Bte & Marie Séguin)
Hope this helps! Bonne Recherche! Happy Hunting!
I have no information about the Lemieux women you mentioned, but I am descended from Charlotte Lemieux who married Jean Baptiste Tougas in St. Constant, LaPrairie, Quebec on July 6, 1806. Is this one of the Lemieux family that you have?

My ancestor, François Desgroseilliers would have married Isabelle and/or Elizabeth Lemieux around 1828 in Laprairie.Around the same time, Joseph Desgroseilliers married Jovite Lemieux. The Lemieux girls were sisters and daughters of Jean-Baptiste and M. Anne Séguin. Could anyone confirm the wedding dates and places and were François and Joseph Desgroseilliers brothers? Thank you.
