Think: according to Wookieepedia, Rey is born by Palpatine's clone, which name is Dethan, one of them at least, and Miramir, Dethan and Miramir wamted to live a usual life, without being special, and palpatine killed them, but a little before they left Rey on Jakku so Palpatine won't manage to find her (if she were on Tatooine, he would, I think this is the first place he searched) and that's why it was so far away from their Sun, or every other planet. Anyway, as her father was not Anakin, that, as it seems, is Palpatine, or anyone else from the Skywalker bloodline, she keeps the title TFSEL (The Fakest Skywalker to Ever Live). But imagine, Luke and Rey are cousins, Rey is Ben Solo's Great aunt (second incest by the Skywalker bloodline, even it's not that close to the first) and way more
