No such thing as a family crest, a crest is only the top part of a Coat of Arms, a Coat of Arms belongs and is awarded to an individual, not their family and not anyone who just happens to have the same surname ..........so if you personally had a Coat of Arms you surely would remember being awarded it...as you don't then you haven't got one http://familytimeline.webs.com/coatofarmsmyths.htm

Heraldry (that's the system of coats of arms, and a crest is a small element of a coat of arms) is a feature of Western European culture - very roughly, the culture of Western Christendom. It derives from the symbols that fully-armoured knights painted on their shields for identification. Thus for example the Austrian and Hungarian nobility - who were Catholic and who in the Middle Ages fought as knights in armour - had heraldry: but the Serbs, being Orthodox, didn't have heraldry at all. When the southern Slav states gained independence at the end of the 19th century they started to invent coats of arms for their monarchs and their cities, just to be have the same as western European monarchies and cities, but this was blatantly a borrowing of a foreign custom.

So - unless your family were renegades who supported the Austrians or Hungarians and were so important that they were ennobled by them and given an Austrian or Hungarian noble title and a coat of arms to go along with it - there is no chance that your family ever had a coat of arms.

There is probably no crest unless you are from a rich family. Oh, I know this guy with the last name Mirkovic! His name is Milos.

If you had one, you would know what it is. Most of us had dirt poor farmers for ancestors, so it is highly unlikely you have a coat of arms.
