My Rey theroy

OK who else left the force awakens thinking who the hell is this Rey girl. my theory is simple and sweet. Remember back to when she touches Luke's blue light saber and she has loads visions. Well in one of those visions she is as a child crying and is held by that guy from jakku so my simple theory is that she is definitely of some relation to kylo ren (episode v reference Luke = Darth Vader's son) probably daughter or niece i think this because she basically hallucinated lukes life but with Ren as her Father. However my friend thinks that she is obi wan kenobi's daughter. But was he not he a jedi and most of the Jedi are not allowed to have children ( Ki-Adi-Mundi was allowed to due to the low fertility rate of his kind.

I would love to hear your ideas leave one in the comment section and as always keep reading.
