Praenomina Used By The Gens
The Manlii used the praenomina Publius, Gnaeus, Aulus, Lucius, and Marcus. The Manlii Torquati also favored the name Titus, using primarily that, Aulus, and Lucius.
A well-known story relates that after Marcus Manlius Capitolinus was condemned for treason, the Roman Senate decreed that henceforth none of the gens should bear the praenomen Marcus. However, this legend may have originated as a way to explain the scarcity of the name amongst the Manlii, as the name was occasionally used in later generations.
