Modern invented name, possibly meaning jaybird or healer
Jalyn is a modern American creation, likely formed by combining the name Jay with the popular suffix -lyn. While it is often used as a creative variant of Jalen, it can also be interpreted as a combination of the bird name Jay and the Welsh element llyn, meaning lake.
