Nero Julius Caesar

Nero Julius Caesar Germanicus (c. AD 6–AD 31) was a close relative of the Roman emperors of the Julio-Claudian dynasty.
Nero was born around AD 6, to Germanicus and Agrippina the Elder. His paternal grandparents were Nero Claudius Drusus and Antonia Minor, daughter of Mark Antony and Octavia Minor. His maternal grandparents were Marcus Vipsanius Agrippa and Julia the Elder, daughter of Augustus.
Nero's siblings included four brothers (Tiberius and Gaius Julius, who died young; Drusus Caesar; and the future Emperor Caligula) and three sisters (Agrippina the Younger, Julia Drusilla, and Julia Livilla). In 20, he married Julia (daughter of Drusus the Younger), daughter of Livilla and Drusus "Castor" (Tiberius' only son by Vipsania Agrippina). Though earlier he was betrothed to the daughter of Creticus Silanus, one-time governor of Syria.
His father Germanicus was heir apparent to his own adoptive father Emperor Tiberius, but Germanicus predeceased the Emperor in 19. He was replaced as heir by Drusus, his father-in-law. But he too predeceased the Emperor on September 14, 23.
Nero was the oldest adoptive grandson of Tiberius, and was seen as the emperor's most obvious successor. However, he was accused of treason along with his mother in 29. Nero was exiled to the island of Ponza where at some time before October 31 he was either induced to commit suicide or else starved to death.
