(French) form of Christina. It was popular in the medieval period, when it appears to have been used interchangeably with Christian, and again in Britain at the end of the 19th century. In the United States it was particularly popular from the 1950s to the 1970s.
English: from a Middle English personal name or nickname. The personal name existed in Old English, and is probably derived from Old English prim ‘early morning’ (from Latin primus ‘first’, used as the name of one of the canonical hours). The surname may be derived from this word as a Middle English nickname in the sense ‘fine’, ‘excellent’.
