Baby will always know that they have a good heart with this name. Cailen, a girl's name, is a variant of the Old French and Greek Caitlin, which means "pure." Caitlin, Katelyn, and all their variations give the name a friendly, familiar feel, but the distinctive spelling of Cailen helps it to stand on its own two feet. Cailen might also be a variation of the Irish word cailín, sometimes anglicized as the name Colleen, which means "girl," transforming it into a sweet moniker for a daughter.
