From the Greek word melissa ‘honey bee’. It is the name of the good witch who releases Rogero from the power of the bad witch Alcina in Ariosto's narrative poem Orlando Furioso (1532). The name was fairly popular in the 1990s, along with other girls’ names sharing the same first syllable.
German and Jewish (Ashkenazic): variant of Buch, with the addition of Middle High German man ‘man’. In some instances Buch may have been used as a nickname in the sense ‘book’, as an occupational name for a scholar or scribe.
