I’m dead set on the name [name]Mario[/name], but I can’t seem to decide on a middle name for him. I personally want a unique/uncommon middle name to go with it, any suggestions? 
A lot for me depends on the last name… but I think that the following sound nice.
[name]Mario[/name] [name]Antoine[/name]
[name]Mario[/name] [name]Byron[/name]
[name]Mario[/name] [name]Donovan[/name]
[name]Mario[/name] [name]Gideon[/name]
[name]Mario[/name] [name]Sebastian[/name]
[name]Mario[/name] [name]Judah[/name]
I think [name]Mario[/name] is like [name]Marie[/name]…It can go with anything.
