Gnaeus Domitius Ahenobarbus, a member of the noble Ahenobarbus family, accompanied his father at Corfinium and Pharsalus, and, having been pardoned by Julius Caesar, returned to Rome in 46 BC.
Gnaeus Domitius Ahenobarbus (11 December, 17 BC - January 40 AD) was a close relative to the Roman Emperors of the Julio-Claudian dynasty. Domitius was the only son to Antonia Major (niece of Roman Emperor Caesar Augustus and daughter to Augustus' sister Octavia Minor to Mark Antony) and Lucius Domitius Ahenobarbus (consul 16 BC). His only siblings were Domitia Lepida Major and Domitia Lepida Minor, mother of the Empress Valeria Messalina.
Gnaeus Domitius Ahenobarbus was a consul of Rome in 192 BC.
