Ashleigh looks over-elaborate and messy, like a
Christmas tree with every available decoration plus a few strings of blingy beads.
I don't mind
Ashley, though it is dated. It retains some elegance, which Asheleigh lacks. I'd like to see
Ashley Susannah or
Ashley Suzette, depending on the ln.
I like
Leigh as a girl name, at least partly because I was at school with a wonderful
Leigh! For a boy I suppose I prefer
Lee without actually liking it, in spite of my excellent nephew.
