I really like it! Its a great Irish name, but it does look like a creative spelling of
Kaylin and would be pronounced exactly like it in English. Unfortunately it sounds really girly. On a girl, it would seem like
Kaylin but More Creative, I guess, which was inspired by
Kaitlyn which was inspired by
Caitlin. It does look trendy. But the name is much older than that and deserves more love. It might catch popular for girls, and it'll lose unisex value in the US, if people even dared name a boy that in the US. Unisex names are really popular here - especially for girls. And then masculine usage gets buried alive.
