Julia Drusilla
Agrippina was the first daughter and fourth living child of Agrippina the Elder and Germanicus. She had three elder brothers, Nero Caesar, Drusus Caesar, and the future emperor Caligula, and two younger sisters, Julia Drusilla and Julia Livilla. Agrippina's two eldest brothers and her mother were victims of the intrigues of the Praetorian Prefect Lucius Aelius Sejanus.
