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.
English: topographic name for someone who lived by a castle or city gate, Middle English burgate, or a habitational name from a place named Burgate, from Old English burh-geat with the same meaning, examples of which are found in Hampshire, Suffolk, and Surrey.
