My official first name is Grzegorz ['??????]. However, it is very difficult to pronounce correctly if you are not a native Polish speaker. Digraph rz stands for a Polish phoneme that is somewhat similar to the one represented by s in vision. Both Grzegorz and Greg originate from Latin Gregorius.

I'm not sure about the origin of the name Kondrak. It's not similar to any Polish words. My theory is that it comes from a mispronounced first name Konrad, although it's not a common first name in Poland. My grandfather's family was from the Kielce region in Poland. There are many other Kondraks there.
