The gens Titurnia was an obscure plebeian family at ancient Rome. Few members of this gens are mentioned in history, but others are known from inscriptions.
Praenomina
The main praenomina of the Titurnii were Gaius, Marcus, and Lucius, the three most common names at all periods of Roman history. Other praenomina found in this family include Quintus, Titus, and Decimus, of which Quintus and Titus were common, while Decimus was more distinctive.
Branches and cognomina
Several of the earlier Titurnii came from towns in Venetia and Histria, but the great majority of inscriptions from this family show that they settled in Roman Africa at an early date, prospering there until at least the second or third century.
