Also, with last nights episode, that leaves even more things uncertain. the "Conceived, not born" will work for Alex and Phil, Jr. But I think we also have to assume that the only people returned to the EF  in going home were those that were within the confines of Storybrooke that belonged to the EF (or other worlds). We don't know what happened with Ingrid between curses, but based on what we've seen so far, both Ursula and Cruella remained in the LWM and were NOT pulled back to the EF.

Also, by the rules stated above, Lily is a native of the EF (she was conceived in the EF, and in fact her egg started hatching right before she was exiled to the LWM, so in some ways you might say she was born in both worlds).

I think a little clarity on the matter may be in order here.
