Naming a sibling...

[toxicthoughts.livejournal.com]

My son's name is Cannon, and my husband and I are discussing names for future children that go with Cannon. Cannon isn't a common name, so we would like another boy's name that isn't common either (but not too far out there although he probably wouldn't mind). He suggested Park and all I can think of when I hear that name is an actual park. It was vetoed. I just can't think of anything that would work. Any suggestions?

For girls, it will definitely be more "normal" since I actually get to pick it. Right now I am stuck on Lila.
