Julia's marriages

Julia, daughter of August, was born in 39 BC. In 25 BC, she was married to her cousin Marcellus, son of Octavia, born in 41 BC. The latest died of illness two years later. She had to be married again: she had August's blood in her and had to transmit it to a mail heir. Hence, a year later, Julia was married to August's old companion, Agrippa, aged 41. Agrippa died in 12 BC and the year after, Julia was married a third time
to Tiberius, born in 42 BC.
