Hello, Have you check any death records for your Haupert family? There is a microfiche of Wisconsin deaths available thru the LDS Church at the nearest Family History Center you can get for 15 cents a sheet. Some Wisconsin county libraries might have these microfiche too. These microfiche lists names, deathdates and other info that you could then write to Vital Records, P.O. Box 309, Madison, WI for a death certificate or go to the county clerk or register of deeds. By comparing the father and mother listed on the death certificates you could find out if they were related. If you have already done this and the death certificates were incomplete then there must be obituaries. There are some films of newspaper obituaries called Wisconsin Necrology that can be rented from the LDS Church's family History center. Go to www.familysearch.org to see which film would help you the most. Hope this helps, Jane
