Langlois
A French surname meaning “the Englishman.”
The #4,719 most common surname in the United States (2010 Census) — about 1 in every 41,095 Americans shares it.
Etymology
Langlois comes from Old French l’Anglois, meaning “the Englishman.” It ultimately goes back to Latin Anglĭcus/Anglus, “English,” with the French masculine ending -ois. In older spelling and pronunciation, the initial l’ often fused with the noun, producing forms such as Langlais and Langlois.
History
The name arose in France as a label for a man of English origin or association, and it became a regular hereditary surname there. The historical sources note that it was common in France and occasionally appears in England as an imported French name. English records also show early spellings like L’Angleyse or Lengleyse, reflecting the same source form.
