I  doubt Rumple found her during his NYC Visit. He spent his time trying to locate Ursula and Cruella. Particularly since, unlike the QOD, it seems that Lily and her adoptive family did not hang around the NE area. Remember that Emma encounters Lily in Hopkins, MN. So it would probably take quite a bit to find her.

I see Ursula possibly returning and rescuing Lily and dropping her off at the adoption agency, but that is about the extent of it. and that still would not explain why the ladies lied about finding Lily.
