1. Daughter of M. Livius Drusus, consul B. C. 112, and sister of M. Livius Drusus, the celebrated tribune of the plebs, who was killed B. C. 91. [See the genealogical table, Vol. I. p. 1076.] She was married first to M. Porcius Cato, by whom she had Cato Uticensis (Cic. Brut. 62; V. Max. 3.1.2; Aur. Vict. de Vir. Ill. 80; Plut. Cat. Mi. 1.2), and subsequently to Q. Servilius Caepio, by whom she had a daughter, Servilia, who was the mother of M. Brutus, who killed Caesar. (Plut. Brut. 2, Caes. 62, Cat. Min. 24.) Some writers suppose that Caepio was her first husband, and Cato her second.
