I have found different informations for Marie Marguerite Plourde
Don't know if this is your Marguerite Plourde but here is what I found
Marie Marguerite Plourde (daughter of Pierre & Virginie Anglehart) born nov. 11, 1867. This one would have been
Joseph Plourde's sister who was my gr-grandfather. (from the Book "Les Registres de St-Godefroi")
the other Marguerite Plourde I have would be the daughter of Joseph Plourde and Marie Marcelline Leblanc. This I have from an old note book that belonged to Lucille Plourde who was Marguerite's sister. in this book it says she was born Nov. 6 1883. The parents of Joseph Plourde is also Pierre & Virginie Anglehart.
Pierre's parents are Jean Baptiste & Marguerite Acou
