What name should we go with? Etzio...

Erin • Mother to 4 boys & Wife to an amazing man! Living in Utah from Cali.
Found out we are having another BOY yesterday and we can't figure out a middle M name... So would love input!
My first son's name is 
Elijah Mason
So it can't be Mason. 
But any other M name suggestion is welcome. 
We are going with Etzio (et-zee-oh) as a first name
