Cadet branches
The House of Hanover is a cadet branch of the defunct House of Welf, the original cadet branch of the Estes.

The House of Este ([ˈɛste] Italian: Casa d'Este, originally House of Welf-Este) is a European princely dynasty.

The elder branch of the House of Este included the dukes of Brunswick and Lüneburg (1208–1218) and produced Britain's Hanoverian monarchs and one Emperor of Russia (Ivan VI).

The younger branch of the House of Este included rulers of Ferrara (1240–1597), and of Modena and Reggio (1288–1796).

According to Edward Gibbon the family originated from the Roman Attii family, which migrated from Rome to Este to defend Italy against the Ostrogoths. However, there is little evidence to support this hypothesis. The names of the early members of the family indicate that a Frankish origin is much more likely. The first known member of the house was Margrave Adalbert of Mainz, known only as the father of Oberto I, Count palatine of Italy, who died around 975. Oberto's grandson, Albert Azzo II, Margrave of Milan (996–1097) built a castle at Este, near Padua, and named himself after the location. He had three sons from two marriages, two of whom became the ancestors of the two branches of the family:
