Hey all! 
So! I don't know if all of you have already know, but Draco Malfoy's wife in the epilogue was revealed by J. K. Rowling to be Astoria Greengrass, a character who doesn't appear in the original series, but is actually the youngest sister of Daphne Greengrass, Slytherin classmate of Malfoy, Harry & co. Although she's a pure-blood, much like the Malfoys, Astoria doesn't share Lucius and Narcissa's anti-Muggle ideologies, and that's the main reason the Malfoy parents didn't exactly approve of her as a daughter-in-law. Can you imagine? Malfoy, being a rebel to his parents by marrying someone actually decent?
The couple also had 1 son, Scorpius Hyperion (yes, weird star-themed names ran in the family, apparently 
), who appears in the epilogue! And, since Astoria insisted on raising him without the "pure blood" ideology, there was always a bit of tension during family dinner with the grandparents Future Malfoys sound huge fun 
What are your thoughts? I'm kinda neutral to Drastoria, but there sure is lots of fanfiction potential to it...
