Caoilinn

This looks fine to me but it is already complicated so you might as well go all the way and use the original Caoilfhionn.

My name is Caoilinn. For anyone reading this I just want you to know it's a great name. If you have the name Caoilinn and you think it's different or unusual you're right, it is. But it's also really cool because none of your friends have the same name and you don't have to write your last name on projects or cards, people just know it's you. It's unique.

This is a beautiful name. I love that it is so different than anything I ever hear. I actually know a little Caoilinn, though we live in the U.S. so she pronounces it like kay-oh-lynn and everyone calls her Caley (Kay-lee). I still love the Key-lynn pronunciation. A stunning name.

In my opinion one of the most beautiful Gaelic names. It's so beautiful and not very common. I definitely want to use this someday.

Elegant and beautiful. Caoilinn has a lovely ring to it. I love the sound of Caoilfhionn, but I find the "fh" redundant looking, so perhaps I prefer this spelling.
