Anglicized form of Carolus (see Charles), or of its feminine derivative Carola. It has never been common as a boy's name, and has become even less so since its growth in popularity as a girl's name. This seems to be of relatively recent origin (not being found much before the end of the 19th century). It probably originated as a short form of Caroline.
German: perhaps a respelling of North German Voges, a variant of Fochezer, an occupational name for a baker (of cakes), from Late Latin focatia (Italian focaccia) ‘(kind of) cake’, ‘(kind of) white bread’.
