I have a bit on the Peladeaus; your Alfred's brother Guillaume, sister Olivine, and nephew Laurent (Chrisoloque's son) all ended up in the Emeryville/Berkeley area of California. Guillaume's daughter Genevieve married a Brennan.
I have Alfred Osborn Peladeau born 30 Jan 1849 in St Luc, Quebec to Theodore Peladeau and Genevieve Moreau, one of the youngest of at least 11 children.
I didn't have Virginia's marriage; thank you for listing it here.
I see your message is about 9 years old so you may not still need any Peladeau info, but you're welcome to email at chris at brennan-families dot com if you'd like to compare notes.
