Aiden Jace or Jace Aiden are both nice.

I'm not a fan of Haley or Kayliegh.

I now lots of name with Ann in them, like:

Keriann
Katiann
Coriann
Teriann
Mariann
Jeriann
Abriann
Morgann
Meghann
Ryann
Canna
Adriann
Loriann
Doriann
Annabelle
Hannah
Annamarie
Rougann

my name is Katie-Ann and i love it.

The middle name Ann goes with alot of names so don't limit yourself unless Kayleigh is your favorite. If it is then stick with it. I love love love the name Jace. That was going to be my son's name but my ex didn't like it so we went with a compromise and named him Garrett ( which I like too). Jace is sounds really masculine and is just different enough without being weird. good choices

My vote is for Kayleigh
