The gens Verginia or Virginia was a prominent family at Rome, which from an early period was divided into patrician and plebeian branches. The gens was of great antiquity, and frequently filled the highest honors of the state during the early years of the Republic. The first of the family who obtained the consulship was Opiter Verginius Tricostus in 502 BC, the seventh year of the Republic. The plebeian members of the family were also numbered amongst the early tribunes of the people.
The orthography of the nomen Verginius or Virginius has been disputed since ancient times; but Verginius is the form usually found in both manuscripts and inscriptions. Modern writers seem to favor Virginius, perhaps by analogy to virgo, a maiden. A similar instance is presented by the nomen Vergilius, which in modern times is often spelt Virgilius.
The early Verginii favored the praenomina Opiter, Proculus, Titus, Aulus, Lucius, and Spurius. In later times they used mainly Lucius, Aulus, and Titus.
All of the patrician Verginii bore the cognomen Tricostus, but they were divided into various families with the surnames of Caeliomontanus, Esquilinus, and Rutilus, respectively. The surnames Caeliomontanus and Esquilinus presumably derive from the Caelian and Esquiline Hills, where these families probably lived. Rutilus is derived from a Latin adjective, meaning "reddish," and was probably acquired because some of the Verginii had red hair. The general Lucius Verginius Rufus, who lived in the 1st century AD, may have obtained his cognomen for the same reason. Although the plebeian Verginii are also mentioned at an early period, none of them had any cognomen. Under the Empire there are Verginii with other surnames.
