Dumais is a French topographic surname from du mais or du meis — 'from the farmstead' or 'from the dwelling,' from the Old French mais (dwelling, farm), derived from the Latin mansus (a house and its lands). It is a characteristic surname of Normandy and Maine — western France — and was carried to New France by some of the earliest Acadian and Quebec settlers.

History and Origins
The Dumais surname developed from the Old French topographic term mais or meis, meaning a farmstead or dwelling with its associated land — derived from the Latin mansus. Families identified as living at the farm or homestead took Dumais as their hereditary surname. The name is concentrated in Normandy (particularly Manche and Calvados), Maine, and Brittany — the western Atlantic regions that supplied many of Quebec's and Acadia's founding families.
Dumais in Acadia and Quebec
The Dumais name arrived in New France with the first generation of Acadian and Quebec settlers in the early seventeenth century. It is among the founding surnames documented in the PRDH at Université de Montréal and in Acadian parish records. The name spread through the St Lawrence valley and through the Acadian communities of what are now Nova Scotia, New Brunswick, and Prince Edward Island.
After the Deportation
Acadian Dumais families were caught up in the Deportation of 1755, like all Acadian families. Some were deported to the British colonies, others fled to Quebec or the Saint John River valley. The family reconstituted itself in the Maritime provinces after the British allowed Acadians to return to the region from the 1760s onward, and remains one of the foundational Acadian surnames.
The French Diaspora
Dumais is established in Quebec and the Maritime provinces from the founding era. The PRDH at Université de Montréal and the Centre d'études acadiennes at Université de Moncton are primary research resources. The Fichier Origine traces Quebec Dumais families primarily to Norman and Maine roots.
From Quebec and the Maritimes, Dumais families spread through the French-Canadian emigration to New England in the nineteenth and twentieth centuries. The name is found in Massachusetts, New Hampshire, and Maine — particularly in the textile mill towns that drew French-Canadian workers. The surname is less common in Louisiana than core Acadian surnames, reflecting its primarily Quebec and Maritime distribution.
How to Research Dumais Ancestry
Dumais research should begin with Normandy — particularly Manche (Archives of the Manche in Saint-Lô) and Calvados (Archives in Caen) — for ancestral French roots. For Quebec, use the PRDH at Université de Montréal. For Acadian Dumais families, use the Centre d'études acadiennes at Université de Moncton. In New England, French-Canadian parish records (held in diocesan archives) and mill town records are valuable for nineteenth-century Dumais emigrants. The Fichier Origine connects Quebec Dumais families to their Norman parishes of origin.
Notable Dumais Families
- Jean-Pierre Dumais (fl. 17th century) — Norman settler and one of the founding Dumais lines in Quebec, documented in the PRDH. His descendants became part of the foundational Dumais family of French Canada.
- Renée Dumais (born 1975) — Quebec journalist and broadcaster, one of the prominent contemporary bearers of the Dumais name in Quebec media.
- Marc Dumais (born 1960) — Canadian Roman Catholic bishop, Archbishop of Moncton since 2012. His position at the head of the largest Acadian diocese reflects the deep roots of the Dumais name in Acadian Catholic heritage.
