Oh, darn. I was going off of pronunciations of others speaking English.
ETA: Intrigued, I just tried online pronunciations on Forvo which purport to comes from people in Poland. And they all sound like "sh" to me. Maybe you and I have a different understanding of "sh?" Or maybe those people aren't really from Poland? I'd be interested in your reaction to the pronunciations of those names at Forvo. :0)
