Middle name for Greyson?

Celena • Married. Mommy to a handsome baby boy. Ohio.

My hubby and I can’t decide on a middle name for Greyson for our little boy. We love the name, but it seems like not much goes with it. Our last name is Griggs. So we definitely don’t want anything with an A - making his initials GAG! I am obsessed with scandal and we wanted it to be Greyson Fitzgerald for the longest time but I think it’s just to long of a name and don’t want to do that to him. But hubby is stuck on keeping it that way. HELP!!! What are some good middle names for Greyson???
