For anyone wanting to do additional research on Milwaukee Kuehl families, there is another resource that helps take the pain and heartache out of local German newspaper research: "Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950). There are about 115 entries or references to Kuehl & Kühl in the index as well as potential leads in spellings like Kuehle & Kühle. Like many valuable research resources, the vast array of these newspapers and the index that has been under construction since 2007 are not online.
