Little is known of her life and sources are confused as to whether her name was "Julia" or "Ilia". There is no satisfactory identification for her. If Julia is correct, she could have been a daughter of Lucius Julius Caesar and Popillia, therefore a sister of future consul Lucius Julius Caesar and Gaius Julius Caesar Strabo. It is also possible that she was a daughter of Gaius Julius Caesar (grandfather of Caesar). Around 110 BC, while both were young, Julia married Sulla. A marital connection to the Julii Caesares may have served Sulla in his political life, as when he was chosen to serve under Gaius Marius in the Jugurthine War. Julia and Sulla had a daughter, Cornelia, who later was active in Roman society. Julia apparently died young, and Sulla married his second wife, Aelia.
