House of Caetani

Caetani, or Gaetani, is the name of an Italian noble family princely family which played a great part in the history of Pisa and of Rome, principally via their close links to the papacy. The Caetani, or Gaetani family has Gothic origins, and descendants of the Dukes of Gaeta. The founder of the house was Marinus I, Duke of Fondi, son of Docibilis II of Gaeta, from which the family gets its name. His successor was Constantine, who took the name Cagetanus and ruled in the latter half of the 10th century. In the late eleventh century, a descendant of his, Crescentius, was duke. This Crescentius was the father of two illustrious people: his successor, Marinus, and his son John (called Gaetanus or Coniulo) from Pisa, who was Pope Gelasius II. Marinus was succeeded by his son Crescentius, who defended his uncle the pope resolutely from imperialist attacks." - [ READ MORE ]
