I would suggest looking in the Polish Genealogy Society of America web pages for the address of the church and have samples of what to write in Polish. The PolishGenWeb site will probably have the same. There is also a very good book, "Polish Roots" I suggest you read it, full of information. I may takes years for a response, depending on the parish. I know a genealogist in Warsaw that will be heading that way in May or June if you would like her e-mail address. I do not know what she charges or if she has time. She is very good and thorough.
