Archambault
A French surname that goes back to an old Germanic personal name meaning roughly “bold, sacred prince.”
The #7,566 most common surname in the United States (2010 Census) — about 1 in every 70,313 Americans shares it.
Etymology
Archambault comes from an old Germanic personal name, usually reconstructed as Ercanbald or Archambald. The first element is commonly taken to mean something like “noble,” “true,” or “sacred,” while the second element is the familiar Germanic bold element, meaning “bold” or “brave.” In French, the name developed into Archambault; related forms include Archambaud and the Italian Arcimboldo/Arcimboldi group.
History
The surname is best understood as a French hereditary form derived from a medieval personal name rather than from a place or occupation. Historical sources note that the name was already in use in medieval France and later spread through French-speaking populations, including immigrants to North America. English-language reference works also record Archambault as a French form of the older Germanic name.
