LaLonde
A French surname meaning “the hill” or “the mound,” originally a topographic name.
The #6,598 most common surname in the United States (2010 Census) — about 1 in every 60,137 Americans shares it.
Etymology
Lalonde is a French surname built from Old French la londe, meaning “the grove,” “small wood,” or in some regional uses a wooded rise or hill. In surname use, it most likely began as a topographic label for someone who lived near such a place. The element is related to older Romance words for a wooded or enclosed tract of land.
History
The name is found in French-speaking areas and later spread to North America, especially through French Canadian families. In modern usage it often appears as LaLonde or Lalonde, with the article fused to the noun. The surname is well established in Quebec and French-descended communities in the United States.
