Think of it another way. The concept of Cinderella is legendary and quite common. All that it is:

A girl has a wicked stepmother (or stepparent) who makes the girl suffer. The girl wishes for a better life, runs into a prince, lives happily ever after.

For an in-show example, The Miller's daughter/Rumpelstilskin (fairytale) is practically a Cinderella story. You have a bad parent, girl in turmoil, a "fairy godmother", a prince that the girl marries.

So, Ella is a traditional Cinderella (Old Disney), but Jacinda could be Cinderella (New Disney), or from another culture.

In real life, we are all bound to run into someone with a similar life as us, right?
