Good name for my characters? PLEASE AND THANK YOU?

This is going to sound weird, but I swear I was going to say Julian for the father even before I looked at the other person's answer! (It's 'cause he reminds me of my friend "Jennifer" and Julian is a similar name) As for the dude, maybe "Derek"? Not exactly usual, but not unusual... Sorry. I'm not being very creative today :-) Whoever said "ZJ", that'd be really cool too since it's ordinary apart, but her nickname for him (the initials) are sorta unique!
