She first married her cousin, the consul Marcus Valerius Messalla Barbatus to whom she bore a daughter, Roman Empress Valeria Messalina. After the death of her first husband, she married Faustus Cornelius Sulla, cos. suff. in 31 and gave him a son, Faustus Cornelius Sulla Felix (who would become consul in 52). At the beginning of Claudius' reign, she married Gaius Appius Junius Silanus, cos. in 28 (who was put to death in 42).

Domitia (aunt of Nero), Domitia Lepida Major. She married, consul and senator Decimus Haterius Agrippa and bore him a son Quintus Haterius Antoninus. Agrippa died in 32. Her second husband was Gaius Sallustius Passienus Crispus, consul suffect in 27, proconsul of Asia and consul in 44 (who later married her sister-in-law, Agrippina the Younger).

Domitia Lepida the Elder

Domitia (PIR² D 171), more commonly referred to as Domitia the Elder -- in fact no ancient source ever calls her Lepida - (ca. 8 BC-June 59) was the oldest child of Antonia Major and Lucius Domitius Ahenobarbus (consul 16 BC), and the oldest granddaughter to Triumvir Mark Antony by Octavia Minor, a great-niece of the Roman Emperor Augustus, second cousin and sister-in-law to the Emperor Caligula, first cousin to the Emperor Claudius, maternal aunt to the Empress Valeria Messalina, and paternal aunt to Emperor Nero. She had two younger siblings: Domitia Lepida and Cn. Domitius Ahenobarbus (cos. AD 32). The date of her birth is not recorded and can be only estimated as no later than 7 BC, but possibly as much as 10 years earlier, if one would allow a long delay between her birth and those of her two siblings.

She married the consul Decimus Haterius Agrippa, who died in 32 as a victim of Tiberius' reign of terror. Domitia bore Agrippa a son, Quintus Haterius Antoninus (cos. AD 53) in approximately 20. In 33 Domitia married the witty, wealthy, and influential Gaius Sallustius Crispus Passienus. Crispus was the adopted grandson and biological great-great nephew of the historian Sallust.

After January 41, Crispus divorced Domitia, so he could marry Domitia's former sister-in-law Agrippina the Younger, who had recently returned from exile. Thereby, Crispus became the stepfather of Agrippina's son Lucius Domitius Ahenobarbus (Nero), who was Domitia's nephew. Crispus soon died mysteriously, leaving a fortune to Agrippina and her son.

During the reigns of Caligula, Claudius and Nero, Domitia was an influential rival to Agrippina. In June 59, she died while confined to a bed with severe constipation. Nero was visiting her at the time, and she commented that when he shaved his beard (a Roman symbolic act, usually performed during a ceremony at the age of twenty-one), she would gladly die peacefully. Nero turned to those with him and joked, "I'll take it off at once." According to a rumor, he then ordered the doctors to administer a fatal dose of laxative to his aunt and seized her property while she was dying. Modern scholars such as Miriam Griffin distrust the claim that Nero poisoned her.
