Question: Zwentibold was a member of a dynasty that was a Frankish noble family with origins in what clans?
Context: The Supponids were a Frankish noble family of prominence in the Carolingian "regnum Italicum" in the ninth century.  They were descended from Suppo I, who appeared for the first time in 817 as a strong ally of the Emperor Louis the Pious.  He and his descendants were on and off dukes of Spoleto, commonly in opposition to the Guideschi clan, another Frankish family powerful in central Italy. The Elder House of Welf was a Frankish noble dynasty of European rulers documented since the 9th century.  Closely related to the Carolingian dynasty, it consisted of a Burgundian and a Swabian group.  It has not been definitively clarified, however, whether the two groups formed one dynasty or whether they shared the same name by coincidence only.  While the Elder House became extinct in the male line with the death of Duke Welf of Carinthia in 1055, his sister Kunigunde married into the Italian House of Este and became the ancestor of the (Younger) House of Welf. Thapa dynasty or Thapa aristocratic family (Nepali: थापा खलक वंश ] ) is a Kshatriya Thapa dynasty that ruled Nepali administration affairs between 1806 and 1837 A.D. and 1843 to 1845 A.D. as Mukhtiyar (Prime Minister).  This dynasty/family was one of the four noble family to be involved in active politics of Nepal together with Shah dynasty, Basnyat family and Pandes before rise of Rana dynasty.  The dynasty was established by leading patron Bhimsen Thapa of the Bagale Thapa clan.  This dynasty gave rise to Rana dynasty of Jung Bahadur Kunwar Rana whose father Bal Narsingh Kunwar was the son-in-law of "Thapa Kaji" Nain Singh Thapa.  Similarly, this dynasty was connected Pande aristocratic family through Nain Singh Thapa who was son-in-law of once Chief Kazi ("Mulkazi") Ranajit Pande. The Rau von Holzhausen are a noble family whose seat was located in Hesse, Germany.  The head of the house of Rau was styled the "Freiherr [Baron] Rau von und zu Holzhausen," although they held several other titles, including an order from the Kaiser that their title, since it was ancient, was to be styled a level higher, thus giving it the title Graf (Count) Rau von Holzhausen.  The family was connected to upper nobility and royalty through a variety of marriages and alliances, most notably through the mother of Queen Victoria of England.  They first received recognition by the Frankish ruler Charlemagne, and were granted a coat of arms.  This honor was in respect of the unwillingness to surrender of a member of the family (since being considered the first lord) during the Frankish ruler's wars eastward through what is now Germany, notably against the Saxons.  Although the Rau family became a well-landed family in Hesse, with their seat at Rauischholzhausen, other estates such as the baronies of Nordeck and Frauenberg, and lands in Bavaria became properties to the noble Lords.  Rauischholzhausen was acquired in the early 14th century, and was in the hands of the family until the 1880s, when it was sold to the Stumm industrial family.  The last Lord Rau von Holzhausen sold much of his property after German unification, and moved out of Germany shortly thereafter, although branches of the family remained influential in Germany for the next century. The House of Rossetti is an Italian noble family appearing in the 14th-15th century, originating among the patrician families, during the Republic of Genoa, with branches of the family establishing themselves in the Kingdom of Austria, and France, and as boyars in Romania.  The origins of the Rossetti family suggest descent from the Della Gherardesca family, a noble family of Germanic origins whose alliance with the Hohenstaufen Emperors had brought the family to prominence in Tuscany, and made them the leaders of the Ghibellines, who feuded against the Guelphs for political control. Zwentibold ("Zventibold", "Swentiboldo", "Sventibaldo", "Sanderbald";  870 – 13 August 900), a member of the Carolingian dynasty, was the illegitimate son of Emperor Arnulf.  In 895, his father, then king of East Francia, granted him the Kingdom of Lotharingia, which he ruled until his death.  After his death he was declared a saint and martyr by the Catholic Church. The Nibelungids were a Frankish noble family descended from Childebrand, the younger full brother of Charles Martel. The Carolingian dynasty (known variously as the Carlovingians, Carolingus, Carolings or Karlings) was a Frankish noble family with origins in the Arnulfing and Pippinid clans of the 7th century AD.  The name "Carolingian" (Medieval Latin "karolingi", an altered form of an unattested Old High German word *"karling, kerling", meaning "descendant of Charles", cf. MHG "kerlinc") derives from the Latinised name of Charles Martel: "Carolus".  The dynasty consolidated its power in the mid 8th century, eventually making the offices of mayor of the palace and "dux et princeps Francorum" hereditary, and becoming the "de facto" rulers of the Franks as the real powers behind the Merovingian throne.  In 751 the Merovingian dynasty, which had ruled the Germanic Franks was overthrown with the consent of the Papacy and the aristocracy, and a Carolingian Pepin the Short was crowned King of the Franks.  The Carolingian dynasty reached its peak in 800 with the crowning of Charlemagne as the first Emperor of Romans in over three centuries.  His death in 814 began an extended period of fragmentation of the Carolingian empire and decline that would eventually lead to the evolution of the Kingdom of France and the Holy Roman Empire. Clam-Martinic is a noble family from the former Habsburg Empire.  It was established when Carl Josef, Count of Clam, a member of the old Austrian noble family Clam, married Maria Anna, Imperial Countess of Martinic ("z Martinicz" or "Martinicové" in Czech), a member of an old Czech Bohemian noble family claimed to be descended from the Vršovci family. The Unruochings (French: "Unrochides" ; German: "Unruochinger" ) were a Frankish noble family who established themselves in Italy.
