Sirois
A French-Canadian surname most often understood as a regional or family-name form that became hereditary in Quebec and neighboring French-speaking areas.
The #8,483 most common surname in the United States (2010 Census) — about 1 in every 79,430 Americans shares it.
Etymology
Sirois is a French-Canadian surname, and its form points to a French personal-name or nickname source rather than an English occupational one. The ending -ois is common in French surnames and can reflect a place-based or family-based form that later became fixed as a hereditary surname. In many cases, surnames of this type entered Canada through early French settlers and then developed distinctive North American spelling and pronunciation.
History
Sirois is especially associated with Quebec and French-speaking communities in Canada, where it became established as a hereditary family name. The surname is also found in New England and other areas with French-Canadian migration. Because spellings were often standardized late, related forms and local pronunciation can differ from family to family.
