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.
Southern Italian: 1. from a feminine pet form of Fisco, itself a reduced form of Frisco, a medieval pet form of the personal name Francesco (from the Latin form Franciscus). 2. from Sicilian fiscella ‘small wicker basket for conserving cheese’, presumably a metonymic occupational name for a cheesemaker or basket maker.
