Ezzo, also Etzo, Ezo, Hetzo, Hezzo or Hezo, is the medieval shortened form of various first names that start with E or He. The diminutive form is Ezzilo (Essilo, Etzilo, Ezilo, Hessilo, Hezzilo, Hetzilo, Hezilo). The shortening of the first names Ehrenfried, Ehrenfeld, Hermann and Heinrich is thereby documented. Historical name bearers are: Ezzo or Ehrenfeld/Erenfried (died before 10 July 963), Count in Bonngau and Keldachgau, father of Herman I, Count Palatine of Lotharingia (ca. 929–996). The latter is the father of: Hezzelin I, also Hezelo (Heinrich, married a daughter of Conrad I, Duke of Carinthia), was Vogt of Kornelimünster Ezzo, Count Palatine of Lotharingia, Count in Zülpichgau (born ca. 955 in the Rhineland; died 5 December 1034) Henry of Schweinfurt (Hezilo), Count of Schweinfurt (died 1017), Count and Margrave of Nordgau, oldest son of Count Berthold I of Schweinfurt and of Eilika of Walbeck.
