Kayleen

Doesn't sound too bad, but Kathleen sounds better and more mature.

The name reminds me of Aileen, which I think is a better name. All you need to do is get rid of the K sound. Plus it sounds less made up than Kayleen.

A better alternative to "Kaylee".

I know a girl at my school named Kayleen. I never heard the name before I met her and I think it's really pretty.

This one basically sounds like a fusion of a girly, cutesy name that suits 7-year-olds much better than 30-year-olds, and of an old-fashioned, ditzy-sounding country girl name.

I think this would be a great alternative to Kayley.

This is a pretty name for a girl.
