What if Rey is Obi Wan’s granddaughter?
How exactly though? They would have to shoehorn in that Obi Wan had a mistress, but the Obi Wan we know was a hermit/monk. It just wouldn’t really flow well into the narrative of Star Wars. The Skywalkers are the only known Jedi to have fooled around.
That would make Rey 35-40 yrs old at minimum. I like it.
If Rey was his daughter, that math would be correct. If she is his granddaughter, as I posited, then she could easily be 19, which is her confirmed age.
