While Cassidy has long been unisex in English, Cassadee is used predominantly for girls in recent U.S. data. The name blends modern stylistic flair (the -dee ending) with Irish heritage, offering a familiar sound with a distinctive look, and preserving the underlying sense of lively, “curly-haired” charm.
