I am looking for information on my great great grandparents who came from Upper selesia area in Poland. The names were Anthony Nanik, Hedwiga Wodarz and Mary Urbanik. My great grandfather Gregor Nanik who married in Jelowa Poland. I have been on several sites and cannot find much on the names. I would like to obtain birth certificates or marriage information. Gregor Nanik was born 9 Mar 1847 and Hedwiga wodarz was 24 Jul 1851.
