Simon Pegg Says That J.J. Abrams Wanted to Give Rey ‘A Relevant Lineage’ That May Not Exist Now Because of Rian Johnson

"Star Wars: The Last Jedi"
Rian Johnson’s “Star Wars: The Last Jedi” broke so many rules in terms of the "Star Wars" universe that we will likely hear countless stories of the process.
Take for example this; In "The Last Jedi" Rey tells Kylo Ren (Adam Driver) that her family  “were nobody.” With Ren adding that “They were filthy junk traders. [They] sold you off for drinking money. They’re dead in a pauper’s grave in the Jakku desert.” 

According to Simon Pegg, who seems to be close-knit bud of Abrams' from “Star Trek” to "Mission: Impossible," Rey's family history was supposed to be very different.  Pegg said that Abrams had another plan:

“I know what J.J. kind of intended or at least was being chucked around. I think that’s kind of been undone slightly by the last one. There was some talk of a relevant lineage for her,” Pegg said. By “relevant lineage,” he surely means to say “belongs to some other recognizable member of the universe.” Johnson nixed it.

No wonder Mark Hamill's been quite vocal with his disapproval to the media.
Simon Pegg confirms what I’ve long heard, JJ had a much different plan for Rey’s parentage. “I know what JJ kind of intended or at least was being chucked around. I think that’s kind of been undone slightly by the last one. There was some talk of a relevant lineage for her.” https://twitter.com/joshuahorowitz/status/981518290739761157 
The Abrams-directed next entry in the “Star Wars” saga is set to be released in 2019, so we'll see if he tackles Rey's parentage in any way then, but, suffice to say, Johnson kind of tied his hands in a knot in that regard.
