Having a baby and need to pick names?

I can tell you like different kind of names, and seeing as how names are people's personal identifiers, it's refreshing to see someone who doesn't want a kid named Bella or Ashley, but something actually unique. However I don't really like any of these. Skylar, Raine, Ava, and Sienna are actually cute, though. I like Sienna the best. So maybe Sienna Louise? Lynne? Sorry I'm not that much of help with middle names.
