Julia Drusilla
Named after her late aunt and her father's favorite sister, Julia Drusilla, Julia was born not long after Caligula married Caesonia (some sources have her being born on the same day as the marriage). The date of her parents' marriage has not been determined for certain, but it is known that it was sometime in the summer of AD 39. When Drusilla, as the child was called, was born, Caligula took her to a temple that housed statues of goddesses and placed her on the lap of Minerva, instructing the goddess to nurse and train his new daughter.
