You are right. Widelka was a very small place when they all immigrated. Now it is a little town. My grandfather on my mothers side was Ploch and they are many of them in Widelka. The part of Widelka called Przekupne. I went there to visit the whole family in late 70's. One of my sisters in law is Buczek and her father was born in Przewrotne. Going to church records would be the best. My cousin told me the book pages were thin and full of hand writen records. The cemetery would be a little more difficult. I wish I can get someone from my cousins to help me get the records. I know the church expects a fee for their records. So far I have not written to anyone about it because they will find it kind of silly.
