In reality, the idea of blood purity is a misnomer – Voldemort himself is a half-blood – and it is unlikely that all of them could be pure-bloods, as very few, if any, such people could exist given the small gene pool. In "Half-Blood Prince", Rowling depicts the Gaunts as a family who are obsessed with their ancestry and driven to inbreeding to preserve its integrity. Rowling has stated on her website that there are no true pure-blood families left but that those who call themselves such simply strike Muggles, Squibs, and half-bloods from their family records. On the other hand, "in rare circumstances" a Muggle-born wizard can become a Death Eater. They are also not above recruiting creatures they deem inferior, as proven by werewolf Fenrir Greyback and the giant clan from continental Europe, as long as they help further the larger Death Eater agenda.
