Baby Girl Names

Dawnya
I'm only 6 weeks but we have a boy's name pinned down. In fact, we had it before we even started trying but a girl's name has been for difficult. We love Ryliegh but can't choose a middle name. Here are our top 3 contenders:
 -Ryleigh Grace
 -Ryleigh Sophia
 -Rlyeigh Evynn
Thoughts on these?  Recommendations on another option? 
We also can't decide on the spelling - Ryleigh or Reilly.  Any preferences?
We have lots of time to figure it out but your help is much appreciated!
