The House of Hohenzollern is a formerly royal German dynasty whose members were variously princes, electors, kings and emperors of Hohenzollern, Brandenburg, Prussia, the German Empire, and Romania. The family came from the area around the town of Hechingen in Swabia during the late 11th century and took their name from Hohenzollern Castle. The first ancestors of the Hohenzollerns were mentioned in 1061.
Hohenzollern-Sigmaringen was a principality in southwestern Germany. Its rulers belonged to the senior Swabian branch of the House of Hohenzollern.

The House of Limburg-Stirum, which adopted its name in the 12th century from the immediate 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.

Stephen I, Count of Sponheim is the patriarch of the Rhenish branch of the House of Sponheim, which ruled over the County of Sponheim. He was closely related to Siegfried I, Count of Sponheim, patriarch of the Carinthian Sponheimish branch, but the exact relationship between the two dynasts is disputed. Johannes Trithemius credits a Count Eberhard of Sponheim as founder of the Abbey of Sponheim and dates the founding to 1044, a position questioned by Johannes Mötsch. The Genealogia Sponhemica presents Count Eberhardus as son of Countess Hedwig and father of a single Count Stephenus I/II of Sponheim. Donald C. Jackman considers Stephen I a son of Siegfried I. Both Jackman and Josef Heinzelmann consider Stephen as being identical to Stephen, Vogt of Worms documented with his brother Markward in 1068. Heinzelmann however casts doubt on a male lineage relationship of Stephen and Siegfried and sees Stephen I of Sponheim as being Lord of Sponheim but not a Count, notices that Stephen I of Sponheim is documented in 1075 as "S(igna) Stepheni de Spanheim" with his seal in a document of Udo, Archbishop of Trier, and proposes Stephen to have married into the House of Sponheim. In another work Heinzelmann considers the Stephen mentioned in 1075 to be Stephen II, or maybe a single Stephen, mentions a Mainzer ministerialis Stephen, the son of Embricho (Emich) and nephew of Archbishop Ruthard, who lived later, as a possible relation, and puts forward that the documented Stephen and Markward belong to the House of the Counts of Metz/Lunéville, which later provided the Vogts of Worms:
"Identisch kann er sein mit einem Wormser Vogt Stephen (1068) [239 UB Stadt Worms I, Nr. 55], der mit seinem Bruder Markwart zu den Grafen von Lunéville/Metz zu gehören scheint, die mit den de Meti später die Wormser Vögte stellen."
The County Palatine of Tübingen was a state of the Holy Roman Empire in the medieval period. The dynasty, originally based in Nagold, managed to acquire extensive holdings over the course of their time in power, distinguishing themselves by founding a large number monasteries in their territories. By the time of the High Middle Ages, several factors contributed to their economic decline, including the expenses of keeping court and extravagant donations to the monasteries they founded. The line itself experienced fragmentation into numerous cadet branches, the longest-lasting of which were the Counts of Tübingen-Lichteck and the Counts of Montfort (1787).
