Possibly set on the names now?

I thought my BF and I had baby names picked but the girl name was not really working for anyone that heard it or with my other children's names. Sooooooo.......here is the new choice. We are really liking this but any opinions are appreciated. The three big brothers are Isaiah, Abraham, and Malachi. If I have a boy he will be named Ezra Mark. If I have a girl we have now settled on Iris Lucille. I know there are other middle names that would work better with Iris but we are pretty determined to use Lucille as the middle name, to name her after her Great Grandmother and we both really like Iris. Thoughts? :)
