This page is where we thank our many sources for Hirning Heritage information. Sources include: The World Book of Hirnings, The Rapid City Daily Journal, Herbert Hirning, Odessa German-Russian Electronic Library, Thomas Hirning for the History of the Hirnings, Wilfred Hirning, Michael Hirning, and others.
More thanks to Dr. Ralf Hirning for researching the Conrad Hirning family tree, Dennis Hirning, Kathy Hirning, Harvey Hirning, Merle Andersen, Otto & Wolfgang Hirning, and others who spent countless hours working to find Hirning Heritage.
Our thanks. Without these sources and the hard work of many people, this page would not be possible.
