when trying to trace your ancestry, nationality can become a misleading roadblock, since it has more to do with political jurisdictions (and those can be very unstable). It is also unreliable to assume that any name comes from just one country. And, when you work with Eastern Europe, those political boundaries were like water. Still are, for that matter.
Your best bet is to look again at your ancestor as an individual, evaluate the exact "facts" about him/her, and find some record that verifies the exact place of where he/she was born. This might be in private family records, possible naturalization records, or you MIGHT find them as on a passenger list via New York. There are also indexes to Ellis Island, if they fit that particular location. Another source (again... specifics are what you need) is maybe any census record in the US. The original images include place of birth, which will be info that is given directly to the census taker.
