Tertinia gens

The gens Tertinia was an obscure plebeian family at ancient Rome. No members of this gens are mentioned in history, but a number are known from inscriptions, largely dating from the second and third centuries.

Origin
The nomen Tertinius belongs to a class of gentilicia formed using the suffix -inius, typically derived from cognomina ending in -inus, but sometimes from other names. Here the root appears to be Tertius, "third", a common surname throughout Roman history. Although a number of Tertii are found in epigraphy from Rome itself, the rest were widely dispersed throughout the provinces, especially in Gaul, Germania, and Noricum.

Praenomina
The main praenomina of the Tertinii were Lucius, Titus, and Gaius, each of which was amongst the most common names at all periods of Roman history. A few Tertinii bore other common names, including Marcus, Publius, and Quintus, while one member of this family in Gallia Belgica bore the rare praenomen Tertius.
