Hi - Zimmerman, Fenstermacher, Haack/Haak, and Shaffer are surnames of some of my ancestors. You'll find the rest of my ancestors on my website, "More Surnames to Brag About," at <A HREF="http://members.aol.com/idkonrad/Mynames.htm"> http://members.aol.com/idkonrad/Mynames.htm</A> If I can help you in any way, please give me some details (given names, dates and places of birth, marriage, death, etc., if known.)
