Titucia gens
Most of the inscriptions of the Titucii are from Sabinum and adjoining regions of Samnium, indicating that the Titucii were probably Sabines, Samnites, or belonged to some other Oscan-speaking people of central Italy. The nomen "Titucius" is presumably derived from the cognomen "Titucus", found in an inscription of the Flavia gens. The praenomina known from the epigraphy of the Titucii are "Titus", "Gaius", "Marcus", "Quintus", and "Manius". All of these were common throughout Roman history, although "Manius", found in a filiation of this gens, was more distinctive than the others—perhaps due to its association with the Manes, the spirits of the dead.
