baby name problems!

We are so close to finding out the gender of our baby and for a girl, we have it figured out and we agree! But we are constantly fighting over a boys name. My husbands father passed away a couple years ago, and I've agreed to let our babies middle name to be his fathers first name. However, I've been dying to call my son Greyson and he thinks the kid will be picked on - in my opinion kids are mean and pick on/get picked on no matter what. My husband wants us to name him Johnathan.
