Need help with spelling

Baby number 3 is on it's way in march. We are not finding out the gender. If it's a boy it's either Colten James or Colten Allen-James. Leaning towards the 2nd one because it's both our dad's middle names. Our 5 year old son picked out Colten. If it's a girl it's Emmaleigh Grace. Nick name would be Emma. However I cant decide on the spelling. It's either Emaleigh or Emmaleigh. What spelling do you like best?
