Limburg-Stirum The house of Limburg Stirum (sometimes referred to as Limburg-Styrum), which adopted its name in the 12th century from the sovereign county of Limburg an der Lenne in what is now Germany, is one of the oldest families in Europe. It is the eldest and only surviving branch of the House of Berg, which was among the most powerful dynasties in the region of the lower Rhine during the Middle Ages. Some historians link them to an even older dynasty, the Ezzonen, going back to the 9th century.
