Catalan (Delós or Delòs): variant of d'Alós or d'Alòs habitational names from any of the towns named with those words as for example Alós d'Isil (in the district of El Pallars) or Alòs de Balaguer (in the district of La Noguera) in Catalonia. French (southern): probably a habitational name for someone from Alos in Ariège or from any of the places in Catalonia (Spain) named Alós or Alòs (see 2 above).
