The Disney Princess 10 Gen Challenge!

I wanna do this challenge but I'm not gonna start with Snow White and her seven kids. I'm gonna start with Cinderella and have her end up being Snow White's or Aurora's mom instead and go from there. I want one of Snows kids to be Ariel since Ariel is the youngest of seven. Ariel might become Mulan or Merida's mom or something. But I definitely want to start with a non royal princess who marries into the royalty first.
