There is one person in the entire series that could be said to have a similar appearance to Rey: Sabé, Padme Amidala's handmaiden, played by Kiera Knightley, who posed as Amidala at various times. I don't know what that means in the end, but I would find it hard to believe that at casting they saw someone who was a previous character's doppelganger and decided to make them a main character without thinking about it.
