Meaning: Powerful; Bright-headed; Slender; Fair; Swamp

There's a lot to love about this lovely girl's name. Anyone who knows their own mind is sure to live up to, and feel emboldened by, the "powerful" meaning of Kellyn. The second meaning of "bright-headed" or "fair" will be extra sweet if baby has light-colored hair. A final meaning, "slender," perhaps from the Irish caol, will serve as a reminder that baby will always be your little one. Kellyn is an alternative spelling of Kellen. It might also have somewhat earthy German roots and come from the word for "swamp," kell.
