It's been a while since your posting so I hope you had a chance to explore the Research Helps at www.familysearch.org
On the left you choose what kind of help and then click the letter of the alphabet. I've learned a lot just by browsing to see what's there.
Try a wild card search on any of the websites you can access. Start by leaving out the "le" in the name--that's the syllable most likely to drop in translation. So, for example, if you search Cze*niewski you'll get a lot more hits, and maybe a hint of where to go with it. If you know as little as a country where anyone with that name lived, it gives you a better shot at narrowing it down once you get your initial responses. I have ancestors with the simplest names that were just MANGLED by census takers, lol. Good luck!
