A Dictionary of Greek and Roman biography and mythology

Κηνσωρῖνος, the name of a plebeian family of the Marcia gens. The name of this family was originally Rutilus, and the first member of it who acquired the name of Censorinus, was C. Marcius Rutilus [No. 1, below], who is said in the Capitoline Fasti to have received this surname in his second censorship, B. C. 265. Niebuhr, however, remarks (Hist. of Rome, iii. p. 556), that this statement is doubtful, as he might have derived it from the circumstance of his father having first gained for the plebs a share in this dignity.
