The Augusta 1 Report post Posted October 30, 2006 Plebians and Equestrians also had three names Equestrians such as Lucius Aelius Sejanus Sejanus is the adoptive form of the name of his gens - Sejanus was a Sejus at birth (like his father of the same name who preceded him as Prefect of the Guard - Lucius Sejus Strabo). At some point in his childhood, perhaps, young Sejus was adopted by a member of the Aelian gens. This was, of course, another way for a Plebeian or Equestrian to acquire a third name or cognomen.
