Marcus Junius Brutus
Also, in June 45 BC, Brutus divorced his wife and married his first cousin, Porcia Catonis, Cato's daughter. According to Cicero the marriage caused a semi-scandal as Brutus failed to state a valid reason for his divorce from Claudia, except that he wished to marry Porcia. The marriage also caused a rift between Brutus and his mother, who resented the affection Brutus had for Porcia.
