Help!!

So we are having a hard time deciding on a baby name for our little guy!! I only have 9 weeks left so I really need to get going on the name thing! I had like 20+ names and I have narrowed it down to 8. I want to know what other people think of the names so please tell me. (don't worry about hurting my feelings if you don't like a name, really it's ok cuz I'm not attached to any) Also if you have any other names that you want to throw out there, please do! Thanks!
