House of Rosier

Rosier is the surname of a family of witches who are supposedly descended from the Originals and, as such, are one of the Sacred Twenty-Eight. The Rosier family is related to the Black, Lestrange, and Malfoy families.

Given these relations, as well as the participation of two Rosiers in Death Eater activity, it is indicative that the Rosiers place great importance on blood purity. They feel disdain for non-magical humans and other witches who were not born with magical gifts, and practice the Dark Arts.
