It's A Girl.....which middle name?

Everybody has seen me post about this about this name before, I'm looking for mn help. We found out the other day we are having a girl. My husband has said we can go with Taryn which has been my favorite name since I was in elementary school. It was the top 2 with our first daughter but we went with the other choice so it will always be on my list until I use it and it always makes it to the top names.

I thought of Taryn Felicity for awhile since I like Felicity as a mn but not a fn. DH likes it as a first name and our dilemma is if we end up having a 3rd girl and we use Felicity as a mn then he will be upset he can't use it for the future 3rd girl but if we don't use it as a mn and have a boy next then he doesn't get Felicity at all which he doesn't like either. I'm going to let him have more of a say in the mn since I got my favorite name. Our first DD is Corianne Wynter (nn Cori).

PS Taryn will be an alliteration with our last name
