Actually, the Vincent name stems from the 80's tv series of Beauty and the Beast. It is widely known Disney lore that the Disney animators referred to the Beast as Adam.
I still stand by my argument that Belle isn't a Princess, but that always leads to a circle argument of "Yes she is!" and "No she isn't!" I'll only say it once here. Jasmine and Aladdin were assumed to be married at the end of the first film, but didn't actually get married until the end of their 3rd film. Belle and "Adam" had a dance, not a wedding. No wedding, no marraige. She's just a lucky Prince-dater in my book.
