Biography
Early life
From his mother’s earlier marriage to Marcus Vipsanius Agrippa he had two older attested siblings, two half-sisters named Vipsania Marcella and Vipsania Marcellina. Some epigraphic evidence suggests he had a sister named Iulla Antonia and a brother named Iullus. Around 1 BC he had probably already been betrothed to a girl of high birth.
In 2 BC his father was charged with adultery with Julia (daughter of Augustus) and was forced to commit suicide. Lucius was sent to Marseille as a result of his father's indiscretion. Lucius was described as a adulescentulus at the time, meaning that he was quite young. He was sent there under the pretence of "studying", and it was not an official exile but was in practise the same as one. Once there he studied law.
