This is for a recent idea that came from my brother. But I might possibly do it in the near future with OC characters that were never mentioned in any of the movies or series.
These are the made up Princesses that I kept in mind.
Princess Isabella of Auradon (Cousin to Mal from the Descendants)
Prince Ollie of Arendelle (Second or third cousin to Queen Elsa and Princess Anna)
Princess Katniss of Coranna (Cousin to Rapunzel)
Prince Allie of North Dakota
Jasper Franklin
Padme Lockwood.
Christopher Stiles
Princess Jessica of Fantasia (Cousin of Ariel)
