Wedding of Draco Malfoy and Astoria Greengrass

"Draco married the younger sister of a fellow Slytherin. Astoria Greengrass, who had gone through a similar (though less violent and frightening) conversion from pure-blood ideals to a more tolerant life view, was felt by Narcissa and Lucius to be something of a disappointment as a daughter-in-law."

- J. K. Rowling regarding Draco Malfoy's future

The wedding of Draco Malfoy and Astoria Greengrass took place sometime after the Second Wizarding War, presumably sometime in the early 2000s. Lucius and Narcissa Malfoy were disappointed in their son's choose of bide, as Astoria held a tolerate view of Muggles and Muggle-borns. The union resulted in the birth of the couple's only child Scorpius Malfoy.

The couple were married for many years before Astoria's death in 2019.
