Tigidia gens

The gens Tigidia was an obscure plebeian family at ancient Rome. The only member of this gens to appear in history was Sextus Tigidius Perennis, prefect of the praetorian guard early in the reign of Commodus, but others are known from inscriptions.

Origin
The nomen Tigidius belongs to a large class of gentilicia formed using the suffix -idius, originally derived from cognomina ending in -idus, but later regarded as a regular gentile-forming suffix.
