Did Augustus Caesar have a wife?

Assuming you mean Marcus Junius Brutus, one of Julius Caesar's assassins, then he had two wives. His first wife was Claudia Pulchra. He was married to her for about ten years before he divorced her suddenly to marry his second wife. His second wife was Porcia Catonis, his first cousin. Porcia is better known as she was the daughter of Cato and Brutus' wife during the assassination of Caesar. She died between 43/42 BC.
