Very very far away from having my own kids (if I ever do!) but....
For girls, I'm currently liking Cassandra (Cassie) and Calista (Cally). I have this thing about being able to make a nickname out of whatever name I choose- my name has a nickname, but I never liked it all that much and most people associate it with a guy's name. I want my kids to have cool nicknames

My first name choice is/was Katharine (spelled that way in honor of Katharine Hepburn), but Tom's sister's name is Kate, so that probably wouldn't be happening if we had kids. I'm very partial to Katelyn for a middle name, though....but then that doesn't really go with my 2 favorites right now...le sigh

I have a much harder time coming up with boys' names....right now I like Alexander and Rhys (since Tom is half Welsh, after all!)
