Servilia had a son named Marcus Junius Brutus (85 BCE to 42 BCE). The Greek biographer Plutarch hints that Brutus was the illegitimate son of Julius Caesar, a result of this long-time affair. Caesar would have been 15 at the time Brutus was born. Many historians also think that Brutus was Caesar's biological son.

Brutus is the most vile of all because Caesar not only forgave him but continued to treat him as his son even after Brutus betrayed him and joined Pompey. Caesar bestowed Brutus with high position almost immediately after the civil war was over. Caesar didn't make himself ``dictator for life''.

Presumably, he's executed alongside the other former elites, but a definitive answer remains unknown. However, Caesar's page on the franchise's wiki mentions an interview with creator Suzanne Collins, claiming that the character survived the events of Mockingjay.

Historically, Cornelia is often stated to have died in childbirth, but this is not confirmed.
