bonsoir Michel, e Your right when you state that Edwidge Neveu's parents were Maxime Neveu and Scholastique Lauzon. correction: Scholastique rather than Colestic.
They were married in Ste-Anne des plaines on 25 Oct 1841.
It appears that Edwidge's parents have emigrated to Michigan where she married Zephirin Morel.This latter couple was not married in Quebec.I have do the research with a Province of Quebec's marriage repertory (BMSA2000) to no avail.
I suggest that you use the data of the Michigan census of 1851 or 1861 to locate Edwidge or her parents and as well as Zephirin Morel.
Let me know if you feel I could be of some help to you with regard to genealogical research in Quebec.Regrettably, my genealogical society does not have research resources for Michigan.
