Tattia gens
The gens Tattia was an obscure plebeian or family at ancient Rome. Few members of this gens are mentioned in history, but others are known from inscriptions. The most illustrious was probably Gaius Tattius Maximus, an eques who rose to become praetorian prefect under Antoninus Pius. Origin
The nomen Tattius is thought to be of Sabine origin, and is listed by Chase among those gentilicia known to be Umbrian, Picentine, Sabine, or from southern Latium. This nomen must be distinguished from that of the Tatia gens, although as both are thought to be Sabine it is possible that they were originally the same. A number of the Tattii known from epigraphy lived amongst the Samnites, who claimed to be descended from the Sabines, and in various towns of Apulia and Lucania. Among the surnames of the Tattii are Vestinus and Paelinus, suggesting that they claimed descent from, or at least affinity with, the Vestini and Paeligni, Oscan-speaking peoples who fought against Rome during the Samnite Wars, and obtained Roman citizenship following the Social War. Praenomina
The Tattii used a number of common praenomina, particularly Marcus, Lucius, and Gaius, the three most abundant names at all periods of Roman history. Other names that occur among this gens include Aulus, Publius, Quintus, and Titus, each of which was also common, as well as the Oscan praenomen Statius. Members
