Meaning and history
Karol is the Polish and Slovak form of Charles, from a Germanic word meaning “man” or “free man.” It is usually masculine in these languages, though similar spellings can be feminine elsewhere. Pope John Paul II was born Karol Wojtyła, and composer Karol Szymanowski is another famous bearer.
Karol rose from #921 to #818 for girls between 1968 and 2005. That year also produced its highest recorded birth count, at 316.
