Waterfall or lake; meadow of hay
Haelyn is a modern American invention, likely created by blending the English surname-name Hayley with the popular 'lyn' suffix. It can be interpreted as a variation of the Old English 'heg' (hay) and 'leah' (clearing), or linked to the Welsh 'haelyn' meaning waterfall.
