_______ Luis ?!?

Me and my so recently found out we're having a boy. Before we had no trouble finding a girls name but are stumped on a boy name. I want to go with Luis as his middle name because it's my so middle name but was wondering if anyone has suggestions for a first name that goes well with that middle name. He's my first so I would love it to be unique and sound well both when saying it in English and Spanish. Any ideas ladies!?
