LeBlanc
A French surname meaning “the white” or “the fair,” originally a descriptive byname.
The #815 most common surname in the United States (2010 Census) — about 1 in every 7,252 Americans shares it.
Etymology
LeBlanc is a French descriptive surname built from le, “the,” plus blanc, “white” or “fair.” The adjective blanc ultimately goes back to a Germanic word meaning bright, shining, or white; older scholarship also compared it with Latin and other earlier forms in tracing the word’s history. In surname use, it would originally have distinguished someone by hair color, complexion, or some other “fair” characteristic.
History
The name is well established in French-speaking regions and is especially common in France and French Canada, where many bearers descend from long-standing colonial-era family lines. In North America, LeBlanc became particularly associated with Acadian and Louisiana French communities. Spelling as one word is common in modern records, though the space-separated form Le Blanc also appears.
