Hi. I'm not related to this family.First of all, Marie Poulin was the 1st wife, as evidenced by Ludger's later marriage to Amanda from the Quebec, Vital and Church Records (Drouin Collection), 1621-1967:
Ludger Boucher (widower of Marie Poulin) m. 12 May 1883 Beauceville, Quebec Marie Amanda Lessard (Benonie Lessard & Marie Doyon)
Here is the baptism for Albertine:
Marie Anna Albertine Boucher, b. 18 Sep, bap 19 Sep 1896 St-Methode-de d'Adstock, Frontenac County, Quebec, daughter of Ludger Boucher & Amanda Lessard. -godparents- Jean Boule & Nathalie Rodrigue, wife of ? Veilleire?.
I don't see any indication that Virginie's parents were Native American. Maybe farther down the line. Hope this helps.Annie
