In case if you really didn't notice, somehow, most of Polish artists, politicians, inventors and so forth (elites, generally) are named either -ski or -cki this is because it means they're descended from the Polish nobility (who once believed themselves to be the only true Poles, and thus the literally-noble Asiatic Sarmatians, as opposed to the Slavic dirty peasants they ruled over).

And a typical Polish Jewish name, which somehow apparently triggered you because you're so stupidly ignorant, will end with -man (often also -baum).
