Hello... Wondering if anyone has the slightest clue about this couples lineage. Married around 1850's. Lived in Douglas, Ontario, and the Pontiac area. Had two children that I know of: Francois Darby (aka Frank Derby)-Married Rosalie Desilets Mousseau and "Oxeel" Darby Proulx. I've been trying to find this for years. Anything would be helpful! Salut!
