Etymology: Wolff is a German surname, a variant spelling of "Wolf" with a doubled f. It comes from Old High German "wolf", the same animal name that gives English "wolf". Medieval German families often took surnames from animals, and a man called Wolf might have been named for a fierce or cunning temperament, or simply for something he was associated with. The meaning you have given, having the qualities of a wolf, is not a sense of the surname. It belongs to the English adjective "wolfish", formed from "wolf" and the suffix "-ish", meaning "like a wolf".
