Love all of your name ideas!
If we have a girl, I love the name Cecilia Joy. My grandmother's name was Cecilia and she was such an amazing, vivacious woman. I also love Cecilia because there are so many potential nicknames and it can go in several directions. CiCi, Cece, Celia, Lia, etc.
I also love Penelope.
I have no idea about boys names though. I guess I have time to figure it out :)
