St. Louis Name Meaning
French: habitational name from any of several places so called (in Aude, Dordogne, Gironde, Haut-Rhin, and Moselle), named with a religious dedication to a St. Louis (see Lewis). In some instances the suffix St may have been an ironic attachment to the family name Louis. As a secondary surname, it is associated with many surnames, including Despres, Doucet, Gaudet, Jourdain, Louis, Roy, and Supernant.
