Plutarch, Antony
Bernadotte Perrin, Ed.

87. Antony left seven children by his three wives, of whom Antyllus, the eldest, was the only one who was put to death by Caesar; the rest were taken up by Octavia and reared with her own children. Cleopatra, the daughter of Cleopatra, Octavia gave in marriage to Juba, the most accomplished of kings, and Antony, the son of Fulvia, she raised so high that, while Agrippa held the first place in Caesar's estimation, and the sons of Livia the second, Antony was thought to be and really was third. [2] By Marcellus Octavia had two daughters, and one son, Marcellus, whom Caesar made both his son and his son-in-law and he gave one of the daughters to Agrippa. But since Marcellus died very soon after his marriage and it was not easy for Caesar to select from among his other friends a son-in-law whom he could trust, Octavia proposed that Agrippa should take Caesar's daughter to wife, and put away her own. [3] First Caesar was persuaded by her, then Agrippa, where upon she took back her own daughter and married her to young Antony, while Agrippa married Caesar's daughter. Antony left two daughters by Octavia, of whom one was taken to wife by Domitius Ahenobarbus, and the other, Antonia, famous for her beauty and discretion, was married to Drusus, who was the son of Livia and the step-son of Caesar. From this marriage sprang Germanicus and Claudius; [4] of these, Claudius afterwards came to the throne, and of the children of Germanicus, Caius reigned with distinction, but for a short time only, and was then put to death with his wife and child, and Agrippina, who had a son by Ahenobarbus, Lucius Domitius, became the wife of Claudius Caesar. And Claudius, having adopted Agrippina's son, gave him the name of Nero Germanicus. This Nero came to the throne in my time. He killed his mother, and by his folly and madness came near subverting the Roman empire. He was the fifth in descent from Antony.
