Last name origins & meanings:

  1. English: patronymic from the personal name Ade, a medieval pet form of Adam.
  2. Jewish (Ashkenazic): it is unclear whether this name is derived from Ades, the Yiddish name for Odessa, or is an English-based Romanization of the Ashkenazic family name Eydes, which consists of the Yiddish female personal name Eyde (a back-formation from Eydl, from Yiddish eydl ‘noble’) + genitive -s. The Ashkenazic family name Adesman presents the same difficulty.
