Many notary records are digitized in Ancestry’s collection, Quebec, Canada, Notarial Records, 1626-1935. This online collection includes Actes, Répertoires, and Indexes des noms digitized from notary records in a massive archived collection in Quebec’s library and archives, the Bibliothèque et Archives nationales du Québec’s (BAnQ). Launched in 2016, this is the result of an agreement between BAnQ and Ancestry. Digitization continues to progress, so keep checking back if you don’t find what you’re looking for. New records are always being added.
