Surname meaning for "Haas"
Dutch, German, and Jewish (Ashkenazic): from Middle Dutch, Middle High German hase, German Hase ‘hare’, hence a nickname for a swift runner or a timorous or confused person, but in some cases perhaps a habitational name from a house distinguished by the sign of a hare. As a Jewish name it can also be an ornamental name or one of names selected at random from vocabulary words by government officials when surnames became compulsory.
