It's so hard to give the correct answer because it sounds like the OP doesn't understand the law/how sales/transfers work judging by the "she didn't have it registered" comment.

Does he really not know, or did he MEAN "transferred" when he said registered.

Lots of life long gun owners think that guns are all "registered" to their owners. I once had a guy semi-whisper to me that he took possession of his father's hunting rifles and that "none of them are registered" - like it was a secret that he was keeping from the government, or something.
There IS NO REGISTRATION in PA.
