Antonia Minor
Drusus married Antonia Minor, the daughter of Mark Antony and Augustus' sister, Octavia Minor, and gained a reputation of being completely faithful to her. Their children were Germanicus, Claudius, a daughter named Livilla ('little Livia'), and at least two others who did not survive childhood. After Drusus' death, Antonia never remarried, though she outlived him by nearly five decades. Three emperors were direct descendants of Drusus: his son Claudius, his grandson Caligula, and his great-grandson Nero.
