Is there a way to get birth records from Poland in 1885 ?
There was no Poland in 1885, but you can try to find the civil registration records in the archives either in Warsaw or (more likely) Moscow. Another option would be to contact the church where your ancestors were baptized. The LDS doesn't have the relevant church books online?
