Tiberius in Wikipedia

Tiberius Julius Caesar Augustus, born Tiberius Claudius Nero (November 16, 42 BC – March 16, AD 37), was the second Roman Emperor, from the death of Octavian Augustus in AD 14 until his own death in 37. Tiberius was by birth a Claudian, son of Tiberius Claudius Nero and Livia Drusilla. His mother divorced his father and was remarried to Augustus in 39 BC, making him a step-son of Octavian. Tiberius would later marry Augustus' daughter Julia the Elder (from his marriage to Scribonia) and even later be adopted by Augustus, by which act he officially became a Julian, bearing the name Tiberius Julius Caesar. The subsequent emperors after Tiberius would continue this blended dynasty of both families for the next forty years; historians have named it the Julio-Claudian dynasty. In relations to the other Roman Emperors of this dynasty, Tiberius was the stepson of the Emperor Augustus, great-uncle of the Emperor Caligula, paternal uncle of the Emperor Claudius, and great-great uncle of the Emperor Nero...
