House of Lestrange

Lestrange is the surname of an ancient family of witches supposedly descended from the Originals and, as such, are a member of the Sacred Twenty-Eight. They are related to the Black, Malfoy, Tonks, Lupin, and Rosier families.

The Lestranges are a very old and wealthy family with vaults at the most secure of banks full of treasures. Like the House of Black, many Lestranges practice the Dark Arts and believe in the notion of pure-blood supremacy, disdain non-magical humans, witches born without magical ability, and those who disagree with their own beliefs. Similar to the Gaunt family, they are willing to intermarry with cousins to maintain their blood purity.
