(French) form of Julia. This was imported to the English-speaking world in the 1920s, and soon became a great favourite. Its popularity was increased in the 1960s by the fame of the British actresses Julie Harris (b. 1925), Julie Andrews (b. 1935 as Julia Wells), Julie Christie (b. 1940), and, more recently, of Julie Waters (b. 1950).
German and Jewish (Ashkenazic): from Middle High German wī(h)rouch, German Weihrauch ‘incense’, hence an occupational nickname for a priest, or a metonymic occupational name for a seller of incense and spices, or, among Jews, mainly an ornamental name. Incense was not used exclusively for religious ceremonies, but was also burnt in the home, as well as being used for medicinal puposes.
