Deletion of Wodzionka (2nd nomination)

Comment: It is a problem finding English language sources, but I did find two mentions: https://books.google.com/books?id=_fRSfmBWWN8C&pg=PA94&dq=%22Wodzionka%22&hl=en&sa=X&ved=0ahUKEwjeoYz4uNDYAhXRuFMKHSa8BN8Q6AEILDAB#v=onepage&q=%22Wodzionka%22&f=false A Fodor's Poland travel guide and https://books.google.com/books?id=XCurCQAAQBAJ&pg=PT108&dq=%22Wodzionka%22&hl=en&sa=X&ved=0ahUKEwjeoYz4uNDYAhXRuFMKHSa8BN8Q6AEIJjAA#v=onepage&q=%22Wodzionka%22&f=false  in a self-published book detailing a day's ration in Auschwitz I think the  exception applies in this instance. I also found https://books.google.com/books?id=fR4_AAAAcAAJ&pg=PA20&dq=%22Wodzionka%22&hl=en&sa=X&ved=0ahUKEwiHj6Cgu9DYAhUB61MKHSkqB544KBDoAQglMAA#v=onepage&q=%22Wodzionka%22&f=false a German-language source from 1847 which mentions the soup. I've added the two English-language sources. And while English sources are preferred, non-English reliable sources may be used as references per , so I suggest adding one or more of the many Polish sources, as well. There is enough now to support
