Colloredo-Mansfeld
Colloredo-Man(n)sfeld is an Austrian (formerly Bohemian) Princely dynasty that, according to family tradition, descends from the Swabian Lords of Waldsee. Allegedly, Liebhart (Liobardo) of Waldsee came to Italy attending King Conrad II and about 1031 was enfeoffed by Patriarch Poppo of Aquileia with Mels Castle near Udine in Friuli. His descendants from 1309 onwards erected Colloredo Castle as their residence.
