Helga (derived from Old Norse heilagr - "holy", "blessed") is a female name, used mainly in Scandinavia, German-speaking countries and the Low Countries. (Hege, Helle, Helge, Helga, Helka or Oili). The name was in use in England before the Norman Conquest, but appears to have died out afterwards. It was re-introduced to English-speaking nations in the 20th century from Germany, the Netherlands, and the Nordic countries. Scandinavian male equivalent is Helge, or Helgi. Eastern Slavic names Olga (Ольга) and Oleg (Олег) are derived from it. Name days: Estonia - May 31, Hungary - October 3, Latvia - October 9, Sweden - November 21, Finland - May 31, Greece - 11 July
