Creuzburg (surname)
Creuzburg (also Creutzburg, sometimes Kreutzburg; in early namings also: Cruce-/Cruciberg, -berch, -burch, -borg) is a German surname derived from an old noble family of knights in Thuringia, Germany. Origins 
Creuzburg is a settlement or place name for the town of Creuzburg, Germany, and in particular a medieval castle Burg Cruezburg from the 12th century nearby. The first element of the name, Creuz, is derived from the Old High German word Kruci or Old Saxon word Kruzi, both borrowed from the Latin word crux (cross). The second element of the name refers to a castle, Creuzburg on the Werra, near Eisenach. The lords of Castle Creuzburg took the name von Creuzburg. The Burgmannen, guards, and fiefs not infrequently also took the name of the Castle. Burgmannen were members of the low aristocracy in the Middle Ages who defended castles. The role is roughly equivalent to the English castellan. Although they were paid for their services, they had to provide their own armour. In the Late Middle Ages, the system of Burgmann disappeared and the castles were protected by Landsknecht. Coat of arms 
The von Creuzburg coat of arms consists of a red eagle on a silver field. On the helmet, two red arms dressed in silver hold a silver ball. The helmet covers are silver and red. References
