Storybrooke character: Unknown
Fairytale Land character: Cora
Fairytale origin based on: Rumplestiltskin (according to showrunner Edward Kitsis)
Cora is Regina's mother. She was once a miller's daughter, but by the time she first showed up in Season 1 she well off; she also has magic. She was generally cruel to Regina, and she conspired to create circumstances in which King Leopold would notice Regina and request her hand in marriage; when it worked, she accepted the offer, regardless of Regina's feelings on the matter. Thanks to a naively given tip from Snow White, she caught Regina trying to run away with the stable boy, Daniel; she ripped Daniel's heart out of his chest and forced Regina to go through with the marriage.
It is unknown if she was alive at the time of the curse; if she was, we have not yet met her Storybrooke character.
