Atilia
Atilia, daughter of Atilius Serranus and first wife of Marcus Porcius Cato Uticensis, whom he married c. 73 BC, after his intended wife, Aemilia Lepida, married Quintus Caecilius Metellus Pius Scipio Nasica.
In the words of Plutarch:
Cato and Atilia had a son Marcus Porcius Cato, who later died in the second Battle of Philippi, and a daughter Porcia Catonis, who became the wife of her cousin Marcus Junius Brutus.
Circa 63 BC, Cato divorced Atilia on the grounds of her "unseemly behaviour", later marrying Marcia. Atilia is not mentioned again.
