Proulx
A French surname most often linked to a medieval nickname or byname, later carried widely into French Canada.
The #6,645 most common surname in the United States (2010 Census) — about 1 in every 60,586 Americans shares it.
Etymology
Proulx is a French surname, and its exact origin is not fully settled in the modern reference tradition. It is generally treated as an old nickname or byname, probably from a French word or dialect form describing someone as clever, dexterous, or spry, though some older explanations are more speculative than others. The final -x is a common historical French surname spelling, often no longer pronounced.
History
The surname is especially familiar in Quebec and other French-Canadian communities, where many French surnames were preserved after migration from France. In North America it also appears in spelling variants such as Prolux and sometimes Prouleau in older records. Like many French surnames, it became more visible in the 19th and 20th centuries through French-Canadian settlement in New England and the northern United States.

Fun fact
In standard French, the final -x in surnames like Proulx is usually silent, so the spelling often looks more elaborate than the pronunciation.
