This website is focused on Wisconsin research, but if you have “cheese heads” in you ancestry, you can’t afford to pass it up.
The link below takes you to the home page where you will find a search form which, once completed, will list for you vital records hits (birth, marriage, death) for pre-1907 Wisconsin.
In addition, a 150,000 name index of biographical sketches, obituaries, and newspaper articles published before 2000.
The hits you get from you search give bare bones information, but also give you the option of ordering a copy of the actual records. If ordering the records puts you off, the index information is often complete enough in itself to give fuel to your research.
