@kala_way - You're totally right about the clunk. The names you suggested work well, they just aren't names we like. Juliet and Adeline/Adelaide get suggested a lot for our sib-set. Charlotte and even Scarlett for that matter is just too popular. If you've got any more ideas shoot em this way, you are on the right track!
@lavenderbelle - Cleo and Cecily are great suggestions! I think we would only use Cleo as a nickname though, possibly for Clementine. Amos and Eames are some of my top middle name picks for boys
@southernbeauty - I'm liking Cynthia but DH isn't a fan.
