Praenomina Used By The Gens
The Sulpicii made regular use of only four praenomina: Publius, Servius, Quintus, and Gaius. The only other praenomen appearing under the Republic is Marcus, known as the father of Gaius Sulpicius Peticus, five times consul during the 4th century BC The last of the Sulpicii known to have held the consulship, in the 2nd century, was named Sextus, a praenomen otherwise unknown in the gens.
