How many Acadians migrated to Quebec territory between 1755 and 1775? How did these families and individuals get there? How were they received? While the answers differ according to researchers, the arrival of Acadian refugees in New France and the province of Quebec remains shrouded in legend. This article aims to shed new light on these questions, while examining the provenance of the myths surrounding historical facts. Our study uses a database created from Catholic registers for the period mentioned and augmented by consulting the University of Montreal’s Programme de recherche en démographie historique as well as the notarial acts featured in Parchemin, a Quebec notarial database covering 1626-1799, developed by the Archiv-Histo Historical Research Society. It is not only a matter of specifying the number and the multiple paths of Acadians who came to Quebec during the Grand Dérangement, but also of identifying the material and socio-political conditions which form the context of this migratory movement at the origin of an important part of the current Acadian diaspora.
