Hayley (and it's variants) remind me of
Halyna. The name just gives me an image of a schoolkid. My favourite is
Hayley or
Hailey.
There's no Hayleys of any spelling where I live. It's a modern English name, I live in Ukraine. But, say there was a
Hayley in a book, it would be written as Хейлі (Kheyli) in Ukrainian.
