The name Xaver is of Germanic origin, derived from the Old High German name Chavor, which in turn comes from the Latin name Xaverius. It is believed to have originated as a variation of the Latin name Xaverius, which was derived from the ancient Roman family name Xavier, thought to mean "new house" or "bright house." The most famous figure associated with this name is Saint Francis Xavier, a 16th-century Spanish priest and missionary who brought Christianity to Asia.
