Julia Caesaris and her husband, the praetor and commissioner Marcus Atius Balbus, had 3 daughters, all named Atia Balba. They were nieces of Julius Caesar, and one of them was the mother of Caesar Augustus.

• Atia Balba Prima was the mother of Quintus Pedius, the suffect consul of 43 BC. Her grandson, also named Quintus Pedius, was a deaf painter beloved of Augustus. He died in AD 13.

• Atia Balba Caesonia (85 BC-43 BC) married the Macedonian governor and senator Gaius Octavius, and by him became the mother of Octavia—Octavius' second daughter of that name, and the wife of Mark Antony—and Octavian, later Caesar Augustus. In 59 BC, Octavius died on his way to Rome to stand for the consulship, and Atia married Lucius Marcius Philippus, the consul of 56 BC and a supporter of Julius Caesar. He loved raising his stepchildren alongside his own son from a previous marriage and arranged Octavia's first marriage, to the consul and senator Gaius Claudius Marcellus. Atia was a religious and caring matron. She had doubts about her son's legitimacy as Caesar's heir. She died during her son's first consulship, in August/September 43 BC. Octavian gave her the highest honours at her funeral.

• Atia Balba Tertia, called Julia, was the mother of Lucius Pinarius.
