Another vote for Charlotte, mainly because I do not like Addison. Addy is cute, but Addison is not feminine to me, and also doesn't go as well with your other kids' names. Off your list, I love the idea of Lucia/Lucy, especially with your other kids...so cute!
I like both of your names but for some reason I don't think they "fit" with Isabella, Rocco, and Anthony. Neither Charlotte or Addison seem like the same style to me. JMO though, not trying to be snarky!
Re: charlotte or addison?
My vote is for Charlotte.
I don't particuarly care for the name Addison though.
