Burchard II of Zollern-Hohenberg
Burchard II of Zollern-Hohenberg (c. 1096–1150/1155) was a Swabian count and the ancestor of the Hohenberg line of the Hohenzollern family. The second son of Count Frederick I of Zollern and Udilhild of Urach, he saw his elder brother Frederick II inherit Zollern after their father died in 1125, while he founded the Zollern-Hohenberg branch, named for Hohenberg Castle near Schorzingen.
He married Helmburgis of Schala-Burghausen, and his sons Burchard III and Frederick held the county of Hohenberg. His great-great-granddaughter Gertrude married Rudolf of Habsburg, the future king of the Romans.
