Rumor had it that Livia was behind the death of Augustus' nephew Marcellus in 23 BC. After Julia's two elder sons by Marcus Vipsanius Agrippa, whom Augustus had adopted as sons and successors, had died, the one remaining son, Agrippa Postumus, was adopted at the same time as Tiberius, but later Agrippa Postumus was sent into exile and finally killed. Tacitus charges that Livia was not altogether innocent of these deaths and Cassius Dio also mentions such rumours. There are also rumors mentioned by Tacitus and Cassius Dio that Livia brought about Augustus' death by poisoning fresh figs. Augustus' granddaughter was Julia the Younger. Sometime between 1 and 14 AD, her husband Lucius Aemilius Paullus was executed as a conspirator in a revolt. Modern historians theorize that Julia's exile was not actually for adultery but for involvement in Paullus' revolt. Livia Drusilla plotted against her stepdaughter's family and ruined them. This led to open compassion for the fallen family. Julia died in 29 AD on the same island where she had been sent in exile twenty years earlier.
