Thanks! DP added another name to the list this weekend that I think I like best: Myla. I had really liked Isla (top on my list), but DP vetoed it. So it seems like Myla is a close and nice compromise. It's also easy to pronounce! He really wants a name with an M in it.
So for Myla I think I'd like:
Myla Pearl (after my grandmother)
Myla Juliet (after DP's deceased mother, Julie)
