Luis Javier is of Spanish origin, derived from the Germanic elements 'Hludovik' and 'Jacobo'. The former translates to 'famous warrior', while the latter means 'supplanter'. It is a compound name, combining two historically significant figures: St. Louis IX of France and Saint James the Greater.
"Luis Javier is quite uncommon; it was given to only five boys in 1988, with no other recorded births of this name since."
