Well, you've got me pegged. It reminds me of the jewelry store Zales, so people would be asking if you named her after the store here. It's also like
Kayla, but for some reason you changed the first letter, so she would be 'different'.
I'd stay away from things like
Pearl,
Golda,
Beryl, .... because of the jewelry connection. I'd say at least one mn should be more common, so she can fall back on one of them.
