The more time I watch, the more sure I am that she's Luke's kid. Unless they're REALLY trying to throw us off.I think it was painfully obvious that Luke is Rey's father. Her insane level of force sensitivity and the connection to Luke's light saber etc. I think Leia knows and that is why she allows Rey to take the MF to go get Luke.
This has probably been discussed but I didn't pick it up the first time - After Rey grabs the lightsaber and has the vision, she's out in the hallway with whoever that old chick is that runs the place. Rey tells her that she has to go home, because her family is going to come back for her. She says that "there is still one that could" and Rey reponds, "Luke?".
Of course this isn't a definitive answer, but why would Rey even mention Luke? Because of the visions she had?
