The gens Fulcinia was a minor plebeian family at ancient Rome.
The first of this name to appear in history is Gaius Fulcinius, one of the ambassadors to Fidenae in 438 BC.
[1] The nomen Fulcinius belongs to a class of gentilicia formed from cognomina ending in the diminutive suffix -inus.
The root, Fulcina, seems to be related to the Latin fulcire, "to support", "maintain", or "prop up".
[2][3] The chief praenomina of the Fulcinii were Gaius, Marcus, and Lucius, all of which were amongst the most common names throughout Roman history.
