I think the sound of
Hayley is lovely. It's not really my type of name at all, but saying it just sounds nice. I don't think it matters which spelling is the "original"-- there are so many spellings out there that no matter what the spelling is, a
Haley will have to spell her name out loud whether it's
Hayley, Haley,or Haielleighh. I like
Hayley better than
Kayley, and I like
Hayley much better than
Haley.
Haylee looks like /HAY lee/ which I like better than /
HALE ee/, which is what
Haley looks like.
