Antonia was born and raised in Rome. By 47 BC, Antonia’s parents had divorced because her mother had slept with her father’s friend, the tribune Publius Cornelius Dolabella.

Antonia’s father had arranged for her to be betrothed in 44 BC, to Marcus Aemilius Lepidus the Younger, the son of triumvir Marcus Aemilius Lepidus. However, for an unknown reason the betrothal was later broken off. In later years, she appeared to have travelled with her father. In 36 BC,

Antonia married Pythodoros of Tralles, who was an Anatolian Greek, who originated from Tralles (modern Aydin, Turkey). He was extremely wealthy and was a friend to the late triumvir Pompey. Pythodoros was about 20 years older than Antonia.

The reason why Antony married his daughter off to Pythodoros was to hopefully gain some of Pythodoros’ wealth for his war chest in his campaign to invade Parthia. This was a testament to Antony’s Eastern perspective, as at that time Antony was married to Ptolemaic Greek Queen Cleopatra VII of Egypt and was living with her at her palace in Alexandria, Egypt.

Antonia and Pythodoros settled in Smyrna (modern Izmir, Turkey). Either in 30 BC or 29 BC, Antonia bore Pythodoros, a daughter and only child Pythodorida, who through her marriages became Queen of Pontus and Cappadocia. Pythodorida was born and raised in Smyrna. After that moment, nothing more is known about Antonia.
