The crown above the coat of arms tells that it belongs to an untitled noble (Adel) family (so not counts of barons etc.) which makes it rather difficult to identify the family. The spoon is German so the best assumption would be that the family is too so if you have time and energy you could browse through the numerous editions of Siebmacher's Wappenbuch. Original editions are from the 17th century but we don't know if the family in question belonged to the old nobility. If they were ennobled for example in the 19th century there are later editions too. You can find links to the various editions in the German Wikipedia page (link below) but it's like trying to find a needle in a haystack especially when the region (like Bavaria, Prussia, Saxony etc.) is no known.
