It's not Luke, Luke was surprised anyone actually showed up on his planet and didn't have a clue who Rey was. I did have the feeling Han Solo knew in 7, when Maz asked him "who the girl is" he had a look on his face and it seemed like Han was about to tell Maz before the scene cut away. I do think Kylo didn't necessarily lie to Rey in 8 when he said her parents were nobodies. Here real parents might have been, being Force Sensitive isn't hereditary, but that also doesn't mean she was never on anyone's radar...
I'm not sure what to think yet.
