Hitstory
The Greengrasses are known to have espoused the philosophy of Pure-blood supremacy, even though, following the horrors of the Second Wizarding War, Astoria Greengrass abandoned those beliefs in favour of a more tolerant world view and even refused to raise her son to believe that "Muggles [are] scum" even though that created tension with her parents-in-law, Lucius and Narcissa Malfoy.

Etymology

 * The surname Greengrass seems to simply come from the words green and grass, emphasising Slytherin's house colours. This would imply the Greengrass family have been traditionally sorted into Slytherin.
