Middle Name Help!

I'm a sucker for coming up with meaningful names and I'm really feeling the name Xavier for my second son. My first is named after my husband so say no more about meaningful there right? lol Well, we both attended Xavier University of Louisiana so the name Xavier seemed fitting for our second little boy. I have another name picked out but I need a middle name for Xavier so I can have two names and name him once he's born after I get to lay eyes on him for the first time. I know that may seem silly, but that's how I did our first boy and I'm glad I did it that way. Anywho, allll of this to ask WHAT'S A GOOD MIDDLE NAME FOR XAVIER? Thanks for your help ladies!!
