Antonia the Elder (born August/September 39 BC) was a niece of the first Roman emperor, Augustus, being the eldest daughter of Octavia the Younger and her second husband, the Triumvir Mark Antony. She married Lucius Domitius Ahenobarbus and became the paternal grandmother of the emperor Nero. Biography Antonia was born in Athens, Greece, and after 36 BC she, her siblings, and her mother were brought to Rome. She was raised by her mother, her uncle, and her aunt Livia Drusilla. According to Cassius Dio, after her father died Augustus allowed her and her younger sister, Antonia Minor, to benefit from their father's estate in Rome. Although little is known of her, Antonia was held in high regard like her sister Antonia Minor, the mother of the emperor Claudius, who was celebrated for her beauty and virtue. Issue Around 23 BC Antonia married the consul Lucius Domitius Ahenobarbus. Three of their children are known for certain: Domitia the Elder - ancient sources refer to her as Domitia. She married the consul Decimus Haterius Agrippa and bore him a son Quintus Haterius Antoninus. Domitia later married Gaius Sallustius Crispus Passienus, consul suffect in 27, proconsul of Asia and consul in AD 44. Gnaeus Domitius Ahenobarbus (PIR2 D127) - consul in AD 32, he married his cousin Germanicus' daughter Agrippina the Younger in 28. Agrippina and Domitius were the parents of the emperor Nero. He was accused by Tiberius, but saved by that emperor's death (Suet. Nero 5) and lived a few years longer under Caligula's reign until he died in AD 40. Domitia Lepida (PIR2 D180) - she first married her cousin, the consul Marcus Valerius Messalla Barbatus to whom she bore a daughter, the empress Valeria Messalina, third wife of the emperor Claudius. After the death of her first husband, she married Faustus Cornelius Sulla Lucullus, suffect consul in AD 31, and gave him a son, Faustus Cornelius Sulla Felix (who would become consul in AD 52). At the beginning of Claudius' reign, she married Appius Junius Silanus, consul in AD 28, who was put to death in AD 42. She outlived her daughter, Messalina. It is also likely that they had another son named Lucius Domitius Ahenobarbus (born between 20 and 17 BC), and possibly also a third daughter (born around 23 BC). Syme thinks its possible that the daughter may have lived to marry and produce children, but probably
