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.
[2] They were said to be one of the noblest families of the Alban aristocracy, and were incorporated into the Roman state after that city's destruction by Tullus Hostilius.
[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.
