Stella Cordillera is a beautiful name! As for a boys name I'm all over the place that's why my husband picked our soon to be sons name: Jaylen Austin
Madison is nice, there are a couple of Madisons in my son's grade school so if you are looking for something that is TOTALLY unique, it's not. But it's cute. Regarding the boy name, I like Jace, Carmen is usually the female form, Carmine is usually the male form of the name.
