We have friends who have Xavier Isaac and it's pronounced Zavier not Xzavier and I love it - sounds funky!.... Mmmm tricky one hun! Zachary Jett is cool too - DH loves Zachary but the teacher in me can't do it - I don't think I can get past the kids at school for some names which really narrows our list! As you know we love Jett too -but can't call our kid after an airline! Good luck!
