Pure-Blood Directory

The Pure-Blood Directory was a directory created in the 1930s that was published anonymously in Great Britain listing twenty-eight families judged to be pure-blood by the anonymous author, who was widely believed to be Cantankerus Nott. He dubbed these families the Sacred Twenty-Eight. A number of families appearing on the list deplored their inclusion, many including the Weasleys proudly noting that they had Muggle ancestors.
