Rosalie for a girl, Leon or Hayden for a boy?

I'm 23 weeks pregnant today and i have settled on a little girls name with my boyfriend. I have been through quite a few boys names in which many people have hated and even said i don't deserve a baby for being unique and saying i try to hard. Anyway which spelling do you like best for the name Rosalie, Rosaly, Rosily or Rosa-lee? I love the sound of this name and would call her Rose or Rosie for short :). Her middle name would be Helen. I have liked mainly the names Leon, Hayden and Rise for a boy. I know, i know.. Rise is a very strange name and i wouldn't use it as it may reflex on the baby when it is older. Which out of Leon and Hayden would you say you prefer even if you do not like either? I cannot decide and nor can my boyfriend so we're quite torn. His middle name would be Jon/John. Thanks!.
