The Great House of Crane was a wealthy and old ennobled pure-blood wizarding family and one of the Sacred Twenty-Nine. They lived in the House of Black and White in Blackmoor, England. The Cranes were related to other notable wizarding families, namely the Dumbledore, Scamander, and Umbridge families. The Cranes were one of the few pure-blood wizarding families that did not hold prejudice against muggles or muggle-born wizards. Because of this, they were derisively called "blood traitors" by other pure-blood houses.
