Burkhard I, Count of Zollern

Burkhard I, Lord of the House of Hohenzollern is considered the first well-documented ancestor of the Hohenzollern dynasty. Because of his name, it has been attempted to link the Hohenzollern family's descent to the medieval Burchardings family, but without success. His father may have been Friedrich, a count in the Sülichgau area. His mother may have been Irmentrud, the daughter of Count Burkhard of Nellenburg.
