Gallius Rax is snoke. Gallius Rax is Rey's farther = Rey is Snokes daughter
He is from Jakku ... and just how Luke was hidden from Vader on Tatooine "they" hid Rey from her farther on his home planet
Lets face it after TFA we all know that the regurgitate stuff in the Star Wars universe.
Gallius"Galli" Rax was a slave child on a desert planet (Jakku) that ran away and was caught and bought before Palpatine (who sensed the force in him) and introduced himself as Sheev, and stating that "an Emperor must have friends."
Eventually, Rax would serve in the Galactic Empire's at Endor among other places.
Supplying the Rebels with info under the code name "The Operator" he provided them the info they needed at Endor. After the Emperor and Vader were dead he Vanished into the Annaj system with Rae Sloan. And the remaining Imperial fleet In the following months, Sloane would attain the distinguished rank of Grand Admiral, bestowed unto her by Gallius Rax. From there, she was given command of the Imperial Navy and became its new commander. Again under the guise of "The Operator" he provided the rebels with the location of a secret Imperial meeting. This basically left him and Sloan in command of what remained of the empire. Which will end up becoming the First Order. Rax idea was to take children and indoctrinating them from an early age into the ways of the Empire (may well have been similar to how the jedi too small children strong in the force)
Blaa Blaa Blaa I could go on and on but IMHO Gallius Rax is Rey's farther and Rae my be her Mother but I cant call that one yet
