On Livia Drusilla's side of the dynasty, Rubellia Bassa was one of the few remaining Claudians who survived the downfall of the first imperial family. A great-granddaughter of Tiberius, Rubellia was the daughter of Julia Livia, whose father and mother were Drusus Julius Caesar (son of Tiberius) and Livilla (daughter of Nero Claudius Drusus), respectively. Rubellia was also related to Augustus by blood through her maternal great-great-grandmother Octavia Minor (sister of Augustus). She married Octavius Laenas, maternal uncle of the emperor Nerva. Her last known descendant was Sergius Octavius Laenas Pontianus, consul in AD 131, who lived during the reign of Hadrian. Afterward, towards Late Antiquity and the Early Middle Ages, the line falls into the realm of parahistory, where various Medieval royal families have claimed some sort of descent, such as the Colonna family and the Orsini family.
