Burkhard I, Lord of the House of Hohenzollern (Latin: Burchardus, Burcardus; born c. before 1025; killed as part of a feud in 1061[1]) is considered the first well-documented ancestor of the Hohenzollern dynasty.
[3] His father may have been Friedrich, a count in the Sülichgau area (roughly corresponding to today's Tübingen district).
Based on this source, Burkhard was killed due to a feud.
The next documented member of the dynasty is Frederick I, Count of Zollern, who was probably a son or a grandson of Burkhard I.
He was the ancestor of Kaiser Wilhelm II, King Frederick the Great, and Queen Wilhelmina of the Netherlands.
