Reviewing records of the locality where your Acadian ancestors eventually settled remains the best way to collect any clues about them. Thus, as nearly all of my Acadian ancestors ended up in Saint-Jacques-de-l’Achigan, local church records proved very useful indeed.
However, if you’re just starting your Acadian lines, I strongly suggest that you look in a library near you for the Dictionnaire généalogique des familles acadiennes from author Stephen A. White. This dictionary covers the period 1636-1714. The information was gathered from parish registers, notary registers, censuses, and other sources from the locations where Acadians lived during their exile.
The good news is that the author, a genealogist from the Centre d’études acadiennes Anselme-Chiasson at the University of Moncton, is still working on Part II of this dictionary which will cover the period 1715-1780. No publishing date has been scheduled yet. We are patiently waiting for it!
