He was born in Rome, Italia, to Nero Claudius Drusus and his wife Antonia Minor. His original name at birth was either Nero Claudius Drusus after his father, or Tiberius Claudius Nero after his uncle, the second Roman emperor Tiberius. The agnomen "Germanicus" was added to his full name in 9 BC when it was posthumously awarded to his father in honour of his victories in Germania. By AD 4 he was adopted as Tiberius' son and heir. As a result, Germanicus was adopted out of the Claudii and into the Julii. In accordance with Roman naming conventions, he adopted the name Germanicus Julius Caesar. - Claudius (1 August 10 BC 13 October 54 AD) was Roman emperor from 41 to 54. A member of the Julio-Claudian dynasty, he was the son of Drusus and Antonia Minor. He was born at Lugdunum in Gaul, the first Roman Emperor to be born outside Italy. Because he was afflicted with a limp and slight deafness due to sickness at a young age, his family ostracized him and excluded him from public office until his consulship, shared with his nephew Caligula in 37. - Livia Drusilla (Classical Latin: ) (30 January 58 BC 28 September 29 AD), also known as Julia Augusta after her formal adoption into the Julian family in AD 14, was the wife of the Roman emperor Augustus throughout his reign, as well as his adviser. She was the mother of the emperor Tiberius, paternal grandmother of the emperor Claudius, paternal great-grandmother of the emperor Caligula, and maternal great-great-grandmother of the emperor Nero. She was deified by Claudius who acknowledged her title of "Augusta". - Antonia Minor ("PIR" A 885), also known as Julia Antonia Minor, Antonia the Younger or simply Antonia (31 January 36 BC - September/October AD 37) was the younger of two daughters of Mark Antony and Octavia Minor.

She was named after her grandmother, Augustus' wife Livia Drusilla, and commonly known by her family nickname Livilla ("little Livia").

Caligula's biological father was Germanicus, and he was the great-nephew and adopted son of Emperor Tiberius.

The normal age to celebrate this was fourteen years . At the age of twelve Gemellus was summoned to the island of Capri where Tiberius lived , along with his cousin Caligula . Tiberius made both Caligula and Gemellus joint - heirs , but it was clear that Tiberius favored Caligula over his own grandson . Livilla had been Sejanus ' lover for a number of years before their deaths , and many including Tiberius believed that both Gemelli were really Sejanus ' sons . Tiberius died March 16 , 37 AD , and Caligula became Emperor . Caligula made Gemellus his adopted son not long afterwards , but ordered him killed in late 37 AD or early 38 AD for allegedly plotting against Caligula while he was ill.
