Daun

The lords of Daun held Daun Castle in the Vulkaneifel. An earlier house died out in 1163, whereupon its ministerialis Richardus de Duna took over its castle and name, founding the second Daun dynasty. In 1250 Wirich of Daun married Gudrun of Oberstein and gained a share of its lordship, beginning the Daun-Oberstein line.

Around 1320 the line built its own castle at Oberstein after quarrelling with the original lords. In 1340 Gilles of Daun received the lordship as a fief from King John of Bohemia, but in 1353 John's uncle, Archbishop Baldwin of Trier, captured the castle and forced the family into Trier overlordship.

A branch acquired Falkenstein in 1456 and became counts of Daun-Falkenstein in 1518; the house became imperial counts in 1643. From 1657 members entered Austrian service, including Wirich Philipp, made Prince of Teano in 1711.
