Look at the information on http://www.jewishgen.org/infofiles/polandv.html
for information on Jewish Records in Poland. The records should be located in the Polish State Archives, but, luckily, the LDS has microfilmed the records before 1880. Check with your local LDS Church for assistance. If you're lucky, there may be an LDS Family History Center in your area. Don't worry, you don't have to be a member of the LDS church to use their facilities.
