Antonia was the eldest daughter of the famous Roman orator Marcus Antonius. Her brothers were Marcus Antonius Creticus (father of the triumvir Mark Antony) and Gaius Antonius Hybrida.
She was the great-aunt of three daughters of the triumvir Marcus Antonius who were also called Antonia. The eldest daughter of the triumvir Marcus Antonius to be named Antonia was the true Antonia major; however, her younger half-sister Antonia, by Marcus Antonius' next wife, about whom much more is known, is also known to historians as Antonia Major. Neither is to be confused with yet another younger sister named Antonia, also called Antonia Minor. Antonia Minor was mother of Germanicus and grandmother of Caligula.
In 100 BC the orator Marcus Antonius obtained a triumph, because he had fought successfully against the Cilician pirates. Some time later his daughter Antonia was kidnapped by pirates from his villa near Misenum and was only released after the payment of a large ransom.[1]
