Carlyn

Carlyn is an English given name that arose as a variant spelling of Carolyn, itself a feminine diminutive form of Carol, which derives from the Latin Carolus, the Latinized form of the Germanic name Karl, rooted in a word meaning free man or full-grown man. The name gained popularity in the twentieth century alongside other feminine elaborations of the Charles-Carol family of names. Related forms include Karlyn, Carolyn, Caroline, and Carlin.
