Tettidia gens
The gens Tettidia, occasionally found as Tettiedia, was an obscure plebeian family at ancient Rome. No members of this gens are mentioned by Roman writers, but several are known from inscriptions. Origin
The nomen Tettidius belongs to a class of gentilicia originally derived from cognomina ending in . Later these names were also formed from other gentilicia, as  came to be regarded as a regular gentile-forming suffix. Where the stem of the original name ended in a vowel, the suffix might become , and sometimes both forms are found alongside one another, as is the case with Tettidius and Tettiedius, evidently formed from the nomen Tettius. The latter name is thought to be of Oscan origin, perhaps from teta, a dove, and in fact most of the inscriptions of the Tettidia gens are from towns in Samnium. Praenomina
The Tettidii used a variety of common praenomina, including Gaius, Lucius, Publius, Quintus, and Titus, along with Numerius, which was uncommon at Rome, but more widespread in Oscan-speaking regions, including Samnium. Members
