Koenig

German (König) and Jewish (Ashkenazic): from Middle High German kūnic, German König ‘king’, hence a German nickname for a servant or retainer of a king (for example, a farmer on a royal demesne); or alternatively a status name for the head of a craftmen's guild, or a society of sharpshooters or minstrels. As a Jewish surname, it was ornamental, one of several such Ashkenazic names based on European titles of nobility or royalty.
