Karolina

Karolina is a Latinate feminine form of Karl, itself derived from the Old Germanic element hari meaning "army" or possibly from a root meaning "free man," cognate with the English word churl. The name spread widely across Europe as a feminine counterpart to Carolus, the Latinized form of Karl, gaining particular popularity in Slavic, Scandinavian, and Baltic countries. It shares its origin with Carolina, Caroline, and Karoline, all of which trace back to the same Germanic root.
