The gens Gegania was an old patrician family at ancient Rome, which was prominent from the earliest period of the Republic to the middle of the fourth century BC.
The gens fell into obscurity even before the Samnite Wars, and is not mentioned again by Roman historians until the final century of the Republic.
[8] The Geganii mentioned in history bore the common praenomina Lucius, Marcus, and Titus, with one example of the rare praenomen Proculus.
[9] The only family of the Geganii during the early Republic bore the cognomen Macerinus, a diminutive of Macer, meaning "lean" or "skinny".
[1][10] Epigraphic sources mention a number of Geganii living under the early Empire, bearing a variety of surnames, but there is no evidence of how they were related to their Republican forebears.
