Marriage. At some point between 2000 and 2005, she eventually married Draco Malfoy, who was two years ahead of her and was a classmate of her older sister, Daphne Greengrass. Lucius and Narcissa Malfoy had disapproved of Dracos choice to take her as a wife, but he chose her anyway and stood up to both of them.
