Anyone with the last name of Stemkowski or Obloj?

My paternal grandparents were from Poland.Just wondering if anyone with either of these two last names are on this site.Unfortunately,I am not familiar with my family tree and also cannot speak the polish language.

STEMKOWSKI: most likely originally Stępowski, toponymic nick for an inhabitant iof Stępów or Stępowo

OB£ÓJ: uncertain -- possibyl derived from the adj. obły = oval, for insatnce an egg-shaped humpty-dumptyesque person??? Without the 'ł', an obój is a musical instrument (oboe).

CORRECTION: The previous entry should read:
STEMKOWSKI: most likely originally Stępkowski, toponymic nick for an inhabitant of Stępków.
MORAL OF THE STORY: Haste makes waste!

I met a business guru from Warsaw called Krzysztof Obłój 3 or 4 years ago. He's got a page on Polish Wikipedia - stick it into an online translator as there's no English page on him yet.
