so, do you have any good source on description of life/culture in poland around that time?
Yes, books from that period. Try
The Labors of Sisyphus by Stefan Żeromski. You can also read
The Peasants or
The Promised Land by Władysław Reymont or
Nad Niemnem by Eliza Orzeszkowa. You're lucky. The end of XIX cent. is a period of realism in literature so there are many novels from that period which describes the life and social problems of that time in very detailed way.
If you are intrested in the earlier period (1811-1812) you can read "Pan Tadeusz" by Adam Mickiewicz.
You need also study history a lot as well...
