Julia Drusilla
A year later, Caligula named his only known daughter, Julia Drusilla, after his dead sister. Meanwhile, the widowed husband of Drusilla, Marcus Aemilius Lepidus, reportedly became a lover to her sisters, Julia Livilla and Agrippina the Younger, in an apparent attempt to gain their support so that he could succeed Caligula. This political conspiracy was discovered during that autumn by Caligula while in Germania Superior. Lepidus was swiftly executed and Livilla and Agrippina were exiled to the Pontine Islands.
