Carlyn

Carlyn is an English name formed as a variant spelling of Carolyn, itself a feminine derivative of Charles, which traces back to the Germanic element karl meaning man or free man. The name gained widespread use in English-speaking countries during the twentieth century alongside related forms such as Caroline, Karolyn, and Karlyn. It carries the same root lineage as the Old High German name Karl, borne by the Frankish emperor Charlemagne.
