Info on Surname "Kupiec"?

Hello, Everyone--
Does anyone have any info on the surname "Kupiec"? I know that it means "merchant," but that's about the extent of my knowledge. Is it a common name in Poland? Is it found in some areas of Poland more than others? Any info would be helpful. Thanks. :-)

Yes your name means merchant ;) good name. The biggest Kupiec's population is in Kraków and Warszawa

Thanks. :-) My grandfather's family was from Poland, and sadly he passed away before I ever thought to ask him about our roots. I thought I'd investigate a little and maybe plan a trip to Poland for my father and myself... It would be nice to connection to our past in some way.
