Tursidia gens
The gens Tursidia was an obscure plebeian family at ancient Rome. No members of this gens are mentioned by Roman writers, but a few are known from inscriptions. Although they gained admission to the Roman senate, none of them rose higher than the rank of aedile. Origin
The nomen Tursidius belongs to a class of gentilicia originally formed from cognomina ending in . Over time,  came to be regarded as a regular gentile-forming suffix, and was applied to form nomina in cases where it had no etymological justification. The earliest Tursidii known from epigraphy came from Spoletium in Umbria, perhaps this family's place of origin. Members
