Julia Drusilla
Sejanus began a series of purge trials of Senators and wealthy equestrians in the city of Rome, removing those capable of opposing his power as well as extending the imperial (and his own) treasury. Germanicus's widow Agrippina the Elder and two of her sons, Nero Julius Caesar and Drusus Caesar were arrested and exiled in AD 30 and later all died in suspicious circumstances. In Sejanus's purge of Agrippina the Elder and her family, Caligula, Agrippina the Younger, Julia Drusilla, and Julia Livilla were the only survivors.
