Oberson is a surname.

It appears there may be a misunderstanding as I cant find a definition for oberson. It may be a name or a typo. If you were referring to Oberon, it is the king of the fairies in medieval and Renaissance literature, best known from William Shakespeares play A Midsummer Nights Dream.
