Boy name, help please!!

So here is a little back story. As soon as we found out we were having a boy, my husband wanted to name baby after him (Donald Clifford III). I told him no way in hell, not even a middle name. This is the absolute only name he would talk about with me. On my own I decided and fell in love with Beckam Drew (could call him Kam for short). As I said, my husband refused to talk names, so I just set myself on this one since I knew my husband wouldn't seriously make me name our son Donald. Now he tells me he doesn't like Beckam. I suggested Maverick and he likes that. He said his name could be Maverick Beckam, but I do not like how that sounds together at all. Long story short...what is a good middle name for Maverick. I feel like it should be short since that's a longer name. Oh and I'm 39 +1 today.
