Feminine form of Cornelius. In the 2nd century BC it was borne by Cornelia Scipionis Africana (the daughter of the military hero Scipio Africanus), the mother of the two reformers known as the Gracchi. After her death she was regarded as an example of the ideal Roman woman. The name was revived in the 18th century.
