1. The sister of Cato Uticensis, was brought up with her brother in the house of their uncle M. Livius Drusus, as they lost their parents in childhood. She married L. Domitius Ahenobarbus, who was consul in B. C. 54, and, like her brother, one of the leaders of the aristocratical party. We learn from Cicero that she was at Naples in B. C. 49, when her husband was besieged at Corfinium by Caesar. (Cic. Att. 9.3.) In the following year, B. C. 48, she lost her husband, who fell in the battle of Pharsalia. She herself died towards the end of B. C. 46, or the beginning of the next year, and her funeral panegyric was pronounced by Cicero, and likewise by M. Varro and Lollius. (Plut. Cat. 1, 41; Cic. Att. 13.37, 48.)
