Which French Provinces the Acadians Actually Came From

By François · Racines Genealogy · Published September 3, 2026

If your Acadian line is in good order you have probably reached the 1671 census, and somebody has already told you where the family came from in France. Poitou, most likely. Aunis or Saintonge. And if you have gone one step further, the Loudunais: that cluster of villages south of Loudun in what is now the Vienne, La Chaussée, Martaizé, Aulnay, Angliers, Oiron.

There is a plaque on the church at La Chaussée. There is a farm museum. Communes in the Vienne are twinned with Acadian towns, and people cross the Atlantic to stand in that churchyard. It is a beautiful story, it is told by serious people, and it may well be substantially true. Nothing in this article is an attempt to take it away from anyone.

What follows is the state of the question: what is established about Acadian origins in France, what is inferred from it, and what is still argued about among specialists. The distinction is not academic. It changes what you do with the next record you find.

What is established

Start with the part nobody disputes, because it is more useful than it looks.

The founding population was tiny. On the account published on the Aménagement linguistique dans le monde site, hosted by the CEFAN at Université Laval, “au total, 89 familles seraient les premiers ancêtres de quelque 300 000 Acadiens”: eighty-nine families are the first ancestors of some three hundred thousand Acadians. That single fact explains why Acadian genealogy works so well on this side of the ocean. A small founding population, heavily intermarried, is exactly the kind of population that can be reconstructed.

The geography has a real shape. The same source gives the centre-west of France, Poitou and Touraine, as accounting for at least half of the first colonists. So the familiar answer is not wrong in its broad outline: the Acadian founders came largely from the Atlantic side of France, and if you are opening a French departmental archive on a hunch, the west is the right place to start.

And the geography is wider than the familiar answer suggests. Twenty-four different French provinces are represented by at least one colonist. That number deserves more attention than it gets, because it is the one that tells you your own family might not be from where the story says.

The recruitments we can actually name

Acadia was not settled by a migration. It was settled by a handful of recruitments, organized by particular men through their own networks, which is why origins cluster at all.

• 1632, Isaac de Razilly. He left France on 4 July 1632 with about three hundred people, mostly men, sailing from Auray in lower Brittany and from La Rochelle. Their exact place of origin is not documented. That is worth sitting with: the founding expedition itself has no established home region.
• 1636, the Saint-Jehan. It left La Rochelle on 1 April 1636 and was the first sailing to carry families rather than men alone. Names aboard include Pierre Martin and Guillaume Trahan, which is why this ship matters to so many trees.
• Charles de Menou d'Aulnay. Born around 1596 near Loches in Touraine, he recruited through the estates and connections he had, and the Loudunais attribution rests substantially on the idea that those connections ran through that country.

The Loudunais question

Where does the Loudunais attribution come from? From the work of a linguist. Geneviève Massignon, in a study published in 1962, argued from the features of Acadian French that its speakers' ancestors came from the centre-west, and specifically from that group of villages. She was a serious scholar and the hypothesis was, and remains, a reasonable one: Acadian French genuinely does carry features that point west.

What has not happened since is the documentary confirmation. The Université Laval page states it flatly: “il n’existe aucune preuve dans les archives françaises attestant l’origine des familles acadiennes dans le Loudunais”, there is no proof in the French archives establishing the origin of the Acadian families in the Loudunais. Of Massignon's data it says they “relèvent de simples hypothèses, non de faits documentés”, are simple hypotheses rather than documented facts, and that her hypothesis “ne repose que sur des similarités”, rests only on similarities. It allows that perhaps a score of families may come from the Loudunais itself, and it concludes that the origin of most Acadian pioneers remains undetermined.

This is a live argument, not a settled correction, and I want to be exact about the limits of what I can tell you. Denis Savard published a critique of the Loudunais attribution in Acadie Nouvelle in 2015, and Jean-Marie Germe published one through Généalogie 86, the genealogical society of the Vienne, which is to say the department that contains La Chaussée. I could not read either piece: both pages defeated my attempts to retrieve them. I have not read Massignon's book either. So what I am reporting is the state of the question as a university reference page sets it out, together with the fact that specialists on both sides of the Atlantic are still arguing about it.

Those who defend the attribution point to individual families whose baptisms in Loudunais parishes appear to match the Acadian censuses. That is exactly the right form of argument, and it is how the question will eventually be settled: one documented family at a time, not by the strength of the tradition.

How to work with this

• Treat the centre-west as a prior, not a destination. It is the right place to look first. It is not an answer about your family until a document says so.
• Keep the other twenty-three provinces open. If the Vienne produces nothing after real searching, that is information, not failure. The founding population came from more places than the story remembers.
• Prefer a documented link over a name match. A passenger or recruitment list, or a notarial act naming a person and a parish, is evidence. A surname in a parish register in the right province is a candidate.
• Prove on the family, not the surname. A French baptism becomes your ancestor when the parents' names, the age and the sibling group all agree with the Acadian record and no rival candidate fits as well.
• Write down what is not established. “Origin in France not documented; centre-west probable; searched Vienne parish registers X, Y, Z without result” is a real finding, and it is what stops the next person in your family from repeating your work.

The route from an Acadian record to a French register runs through the departmental archives, and most of them are online free of charge: see the free French archives online and, for which level of French administration keeps what, how France is organized. For the dispersal itself, and the crossings either side of it, read where the deportation scattered the families and the three crossings. And because a surname is where this question usually reaches a reader in the first place, see what an Acadian surname can and cannot tell you.

Common questions

Did the Acadians come from Poitou?

In large part. The centre-west of France, Poitou and Touraine, accounts for at least half of the first colonists, and the founders came largely from the Atlantic side of the country. But twenty-four French provinces are represented by at least one colonist, so Poitou is where the odds are, not where every family is from.

Is the Loudunais origin of the Acadians proven?

No, and that is not the same as saying it is wrong. It comes from a linguistic hypothesis published by Geneviève Massignon in 1962. A Université Laval reference page states that no proof exists in the French archives for it, that her data are hypotheses rather than documented facts, and that perhaps a score of families may come from the Loudunais itself. Specialists are still arguing about it.

How many Acadian founding families were there?

Eighty-nine families are given as the first ancestors of some three hundred thousand Acadians. The small size of that founding population is why the Acadian genealogy of North America is so well reconstructed, and why any one documented French origin resolves so many trees at once.

Sources and figures. The figures on the founding population, the twenty-four provinces, the share of the centre-west, and the quoted statements about the Loudunais and about Geneviève Massignon's thesis all come from one page: the entry on Acadian origins on Aménagement linguistique dans le monde (archived copy, 4 August 2025), hosted by the CEFAN at Université Laval. That reservation matters more here than anywhere else on this site, so it is worth stating twice: the page carries no credited author, and it is a university-hosted reference site rather than peer-reviewed scholarship. It is quoted here as what it is, and a reader who wants to weigh the question should go to it directly. The 1632 and 1636 expeditions are as described by acadian.org. I have not read Geneviève Massignon's Les parlers français d'Acadie (1962), and I do not cite it for any figure. Denis Savard's 2015 chronicle in Acadie Nouvelle and Jean-Marie Germe's article for Généalogie 86 are named because they exist and are part of the debate; I was not able to read either, and nothing here is attributed to them.
