ANYONE from Russia or know russian cities?

Here's the crux of the issue. When did he leave there? Timeframes for researching in Eastern Europe are everything. Political winds changed entire maps in a matter of weeks. Everyone of these countries at some point has been considered "Russia" by U.S. Immigration in part or in whole: Finland, Estonia, Latvia, Lithuania, Poland, Belarus, Ukraine, Georgia, Romania But I can dispel a few myths. -pola has nothing to do with Poland. Russia never recognized "Poland" and always referred to the area as "East Prussia". The possibilities are multiple. This could be a town along the Pola river. "Janosh" is a very common male name in East-Central Europe. Any of the collar countries I listed above, except maybe Finland, could have named a town after "Janosh" somebody. Pola in Croatian means "half" "Pola" in latin-based languages means town. The internet's not the best place to find the location of lost towns in Eastern Europe. No one really has taken the time to track them all...towns appeared and disappeared too quickly in the last 400 years. But I would suggest you visit a large research library and find the gazetteers, atlases and maps from the different countries under Russian control during the era when your great grandfather lived there. There are also volunteers at many of the ethnic museums and cultural centers who will do lookups, but you can wait up to a year depending on how backlogged they are and how many volunteers they have at any given point in time. The Polish Library in Chicago has such a service for Polish and Lithuanian towns, for example. You could also try contacting the Newberry Library in Chicago to see if a volunteer would be willing to look through their resources for that town. You need to give much more information than you gave here. They would need a timeframe, Grandfather's name, the name of the document from which you pulled this town....context is everything.

Wikipedia doesn't always work and you'll need to find ancient maps to find out that one.

It can be a city in modern-day Poland which used to be part of Russia. Try to look there
