Finally think we have a name..but need help.

It’s been a real struggle for me to pick a name because I had a couple in mind like Vincent, Juan Carlos, Zacarias but bonding with this little one nothing seemed to stick. My husband and sons middle name is Mario. Mario has always liked. We don’t call our son Mario just Luke. So I asked my hubby what about Mario? He said yes. Now I just need a middle name. Any ideas? I prefer a Mexican name as my parents only speak Spanish. Any help would be appreciated. This naming game is tough.
