Ezzo

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:
