Genealogy / Looking for Pilecki's from,or around Gwoznica, or Rzeszow [3]

Our family just found a tape done by my grandfather of where he, and his family grew up in Poland. It shows the school he attended. The church he, and his brothers helped rebuilt. Where our family is buried, ie my great grandmother. My grandfather pasted away in 1999. During our grieving all addresses of Family in Ploand where lost. I think I found my Great-Aunts address. I don't speak, or write Polish. But, I am going to try to contact her by mail. If anyone has any, and all information on the Pilecki's, or Hadam. Please contact me. I think we are family. Also there are about 15 family memebers here in America planning to visit Poland in About 2 years. We would like to meet our cousins in Poland. My grandfather's name was Frank, his Wife is Stella.
