Sorry. I don't have any death information for "Julia" GUERIN a person I assume is the same as Julie GUÉRIN dit St-Hilaire m 11 Nov 185, Saint-Georges-de-Henryville, QC, François L'ECUYER (Pierre/Marie-Rose BOUDREAU).
I have two Armand L'ECUYER and don't know if either can sing. One is the father of Micheline (Mimi) LÉCUYER and is my ninth cousin from the "other" Famille LÉCUYER. The other m 23 Oct 1948 Les Cèdres, QC, Jacqueline COUSINEAU, and is my fifth cousin, twice removed, a descendant of Louis L'Ecuyer et Marie-Cécile Larivière/Rivière.
I don't know which Napoleon you are referring to. I have two: one is the son of Pierre and Marie-Théotiste LANOUE; the other is the son of Narcisse and Marguerite LECLERC. I don't have the information needed to check your other information for him.
It looks like I can't help you. Sorry
