A middle name for our son?

I like Alexander Cale and Alexander Jackson. I would probably go with Cale though due to the fact that he would already have a very long first and last name so do him a favor for the future and make it short. My parents did that for me because my first name is Savannah and last was long to so they gave me a very short middle name. It's already a pain writing all that out without having a long middle name as well.
