Schnick is a German spelled surname. The closest I found to that spelling in Polish is Sznik, but there were no longer any people in Poland by that name in 1990 or 2002.
Another similar in spelling is Sznic, but that would be pronounced Schnits in Polish.
After WWII, most people of German extraction left Poland. Most of them moved into Germany. Go to http://www.google.com
and try to find a directory for the German White Pages, and maybe you can find someone that way.
