Here are some tidbits from the interwebs:
Is Rey a Kenobi?
There is one more possibility: She could be Obi-wan Kenobi’s granddaughter. I had heard early on that the change from Michael Arndt’s script to the one J.J. Abrams was working on with Lawrence Kasdan was that it changed the story from being just about the Skywalkers to being a story about the Kenobis vs. the Skywalkers. Again, that was just a rumor and a lot of what we heard early on was wrong or evolved into something else. But it is possible.
Consider this: Obi-Wan Kenobi was in possession of that lightsaber for three decades, while Luke Skywalker had it only for a year or so. The lightsaber calling to her might have nothing to do with Luke and Anakin Skywalker. Also, while Rey is having her vision
we hear Obi-wan Kenobi say “Rey, you’ve taken your first steps.” Of course, Yoda is also heard during this sequence, but of course he is one of the highest Jedi masters of all time. So the question is, if Rey is a Skywalker — why did Rey hear Obi-Wan in her vision and not Anakin Skywalker?
Later in the conversation Boyega mentioned he loved the fan theory that Finn is Mace Windu’s grandson and enthused about an encounter he had with
Samuel L. Jackson at a party. Going by race alone, Finn could possibly be a descendant of Mace Windu or Lando Calrissian. But do we really need to make this universe any smaller than it already is? I would rather see Finn try to explore his past and find a new story with new characters and not make this galaxy any smaller and too connected by fate.
