Chiasson
A French-Canadian surname, most likely a patronymic form linked to an older personal name or nickname tradition.
The #9,301 most common surname in the United States (2010 Census) — about 1 in every 88,238 Americans shares it.
Etymology
Chiasson is a surname of French origin, especially associated with French Canada and Acadian communities. It is generally understood as a patronymic surname, probably developed from a reduced or regional form of an older personal name or nickname rather than from a common modern French word. The ending -on is a typical French surname suffix, often used to form diminutives or family-name variants.
History
The name is found most often in French-speaking North America, particularly among Acadian and Quebec families. Like many French-Canadian surnames, it likely became established through inherited family naming in the colonial period and later spread with migration within Canada and to the United States. Modern bearers are often concentrated in New England and Louisiana areas with strong French-Canadian or Acadian ancestry.
