Justinia gens

The gens Justinia was an obscure plebeian family at ancient Rome. No members of this gens are mentioned in ancient writers, but several are known from inscriptions, chiefly from Gaul and Germania.

Origin
The root of the nomen Justinius is the cognomen Jūstus, referring to someone known for being "just" or "fair". This was one of a large class of surnames derived from the character of an individual. From the surname arose both Justinus, a diminutive cognomen, and the nomen Justius. Justinius must have been formed from one of these two, using the gentile-forming suffix -inius, which could form new gentilicia from either nomina or cognomina.

Praenomina
The only praenomina associated with the Justinii appearing in inscriptions are Marcus, Gaius, and Tiberius, of which the first two were very common at all periods of Roman history, while Tiberius was favoured by a smaller range of families.
