Chiasson

The surname "Chiasson" likely originates from Viking influences in western France during the Viking Age (late 8th to early 11th centuries). The suffix "-sson" or "-son" in the surname suggests a Scandinavian origin, indicating "son of" in Old Norse. Early bearers of the Chiasson surname, such as Pierre Chiasson, a ploughman, may have descended from Vikings who settled or interacted with communities in regions like La Rochelle and Aunis. These areas were known for their coastal trading and strategic importance, making them likely points of Viking settlement and interaction. Farming became a common occupation among Viking descendants, further supporting the theory of Scandinavian origins for the Chiasson surname.
