Looking for my Hefner relatives that immigrated to the states before 1952 when my dad (Stefan Hefner) did. I have all kinds of information for all of you if your family descends from Katymar, Hungary (a German settlement in Hungary - known as Donauschwaben) My father believes one of his great uncles or uncles came to the US in the 1800's. Some of the names could be Sebastian, Johann, Matthias, Peter, Adam or Stefan. With different spellings of Hefner.
