Karoliina

Karoliina is the Finnish and Estonian feminine form of Carolus, the Latinized version of the Germanic name Karl, which derives from a root meaning man or free man. The name entered Nordic and Baltic cultures through the widespread European influence of Carolus Magnus, known in English as Charlemagne, whose legacy made Karl and its derivatives enormously popular across the continent. Karoliina is the characteristically double-vowel Finnish and Estonian adaptation of the international form Carolina, itself related to Caroline, Karoline, and Karolina used across other European languages.
