Mary Margaret in season 1 != Mary Margaret in season 2 onward, so I don't really get your point.

Belle is a special case. But Belle from season 1 is Lacey. It's like you would say that David before episode 3 is not David but someone else. That's not true. Regina made Lacey with the Dark Curse, but she also gave her Amnesia.

Moreover, if you want to get technical about the surname, the newspaper says "Mr Gold to marry Belle French". Which means it was written before they had wed. Afterwards he clearly calls her Mrs. Gold. So her surname is supposed to be Gold, not French.
