Bah! Sorry, I don't like it on a girl at all. As a feminine name it seems so infantile, much like
Hayley and
Chloe. I was completely surprised to learn that it was so popular as a girls' name in the USA because I couldn't imagine it; I had to do a double take when I heard it used on a young girl at the market. Its popularity for girls has increased rapidly over the past ten years, and I can see it breaking the top fifty. So it's not trashy but definitely trendy.
I think it's down-to-earth and quite sweet on a boy, however. I also think it would age better as a male name. It's not something I would use myself but I find it pleasant enough. And it makes me think of
Hadley Fraser, who has a lovely voice.
Other than that and the female sighting above, I haven't heard the name elsewhere.
