Origin of the name Sergius

Roman family name, possibly meaning "servant" in Latin but most likely of unknown Etruscan origin. Saint Sergius was a 4th-century Roman officer who was martyred in Syria with his companion Bacchus. They are the patron saints of Christian desert nomads. Another saint by this name (in the Russian form Sergey) was a 14th-century Russian spiritual leader. The name was also borne by four popes.
