Caesonia gens
The gens Caesonia was a plebeian family of ancient Rome. They first appear in history during the late Republic, remaining on the periphery of the Roman aristocracy until the time of Nero. Roman empress Milonia Caesonia, the last wife of the emperor Caligula was presumably descended from the Caesonii, as she bore their nomen. Another family of Caesonii attained the consulship several times beginning in the late second century; it is not clear how or whether they were related to the earlier Caesonii.
