Comeau
A French surname, most likely from a nickname or place-name root, especially common in Acadian and Francophone communities.
The #6,115 most common surname in the United States (2010 Census) — about 1 in every 55,045 Americans shares it.
Etymology
Comeau is a French surname, and its exact origin is not entirely settled. It is often treated as a surname formed from an Old French word or local name that later became hereditary, but the precise source is not certain enough to state with confidence here. In practice, the name is strongly associated with French-speaking Canada and Acadian families.
History
The surname is especially well known in Acadian, New Brunswick, and other Francophone Canadian communities, where it has been established for generations. It also appears in French-speaking parts of the United States, particularly in New England and Louisiana, through migration from Canada. Because the name has several possible French roots and no single universally accepted derivation, genealogical sources usually treat its deeper origin cautiously.
