Re: Preuss Family Hemlock, Michigan
Henry's son Martin, about 78 years old, may be living in Midland, MI. Check http://www.infospace.com/home/white-pageshttp://www.infospace.com/home/white-pages for his address.
If that is not the correct person, you could contact the library in Hemlock at http://www.wplc.org/hem/http://www.wplc.org/hem/. There are several PREUSSes still there.
I am not related.
