Arhontoula is derived from the worch archon, neaning a person who rules. The -oula ending is diminutive. So the meaning of Arhontoula, metaphorically could be something along the lines of "little princess".
Hrisopiyi is derived from the words "chryso" meaning "gold" and "pige" meaning "foutain, source or spring." That makes Hrisopiyi a fountain of gold :)
