Middle Name?

[ojitosverdes.livejournal.com]

Well i've decided on a first name for my baby boy, it's Gabriel. Now i'm having a lot of trouble coming up with a middle name for him. I just want something that sounds nice together, and only has one or two syllables, but so far I don't have anything! Any suggestions? I need help!!
By the way, I don't want his initials to spell out G.A.S. (lol) so i've ruled out any middle names starting with an A. =p
