Having just rewatched episode 2 “The Thing You Love Most” I have to say it pretty much confirmed that Rumple and EQ were not married and most likely she did not lose a son. The EQ says in that episode that she was to be married, but SW ruined it all; that she (the EQ) lost what she loved most because of SW; and she blames Snow for taking away her Happily Ever After. Apparently she and Snow have known each other awhile. So with that refreshed info I have in my mind ruled out the EQ and Rumple. Although I did begin to wonder if her mother might have been married to Rumple, and then I remember her father, Henry, was what she loved most in that epsiode, may he rest in peace. I will say that her father kind of fits the bill for a humble miller, perhaps:)
