Marlyn

Marlyn is a feminine name that functions as a variant of Marilyn or a blend of Mary and Lynn. Its origins are diverse, potentially deriving from the Welsh elements 'mâr' (sea) and 'llyn' (lake), or as a feminine form of Marlin.

The name carries a soft, melodic quality while maintaining a classic feel. Though less common today, Marlyn continues to be chosen by parents who appreciate its gentle sound and connection to traditional naming elements while offering a slightly distinctive alternative to more common variants.
