The QC DEATH INDEX (1926-1996) has an 1) Édouard VIBERT, b. 1883-03-14, d. 1968-07-27 in Montréal, QC. Although married, his wife's name isn't given. His parents: É. VIBERT+A.M. LEKEEN 2) Olive BOUDREAU, b. 1907-07-15, d. 1994-04-05 in Montréal, QC. Widow of VIBERT. Her parents: Victor BOUDREAU+P. surname not listed. I doubt the couple was married in 1907, unless the INDEX is in error. Finding the grand-daughter without knowing the name of her parents & thus not her maiden name is quite a feat. Got any more info? I did find the following: 1) Huguette VIBERT (Édouard+Éva DELANGIS) m. 1952-12-20 in La Nativité parish, Hochelaga, a section of Montréal , QC, to Émilien LEBEL (Émile+Blanche CONANT); They could have had a daughter born in 1958, but I haven't found her. On the other hand, there are many Johanne VIBERT, but it's practically impossible to find which one is the grand-daughter of Édouard+BOUDREAU. I haven't found a Johanne LEBEL whose either parent is a VIBERT that would link her to your Édouard+BOUDREAU. Do you have more info for us?
