Tifernia gens
The gens Tifernia was an obscure plebeian family at ancient Rome. No members of this gens appear in history, but several are known from inscriptions. Origin
All of the Tifernii known from inscriptions from outside of Rome came from Umbria, including at least three from the town of Tifernum Tiberinum, Tifernum on the Tiber. Unless the town was named after the Tifernia gens, the Tifernii must have obtained their nomen from their town of origin. Members
