Sergius /ˈsɜːrdʒiəs/ is a male given name of Ancient Roman origin after the name of the Latin gens Sergia or Sergii of regal and republican ages.
It has given rise to numerous variants, present today mainly in the Romance (Serge, Sergio, Sergi) and Slavic languages (Serhii,[2] Sergey, Serguei, Srđan).
Chase hesitantly suggests a connection with the praenomen Servius, probably from an old Latin root meaning "to preserve" or "keep safe".
[4] It became a personal name in Roman imperial times and spread to the Byzantine Empire in the Greek form Sergios (Σέργιος).
It became popular in Christianity in honour of the fourth-century martyr and saint Sergius, especially among Roman ecclesiastics of Syrian extraction, starting in the seventh century.
