There are family death notices for a Wenzel Friedl found in Milwaukee's German newspapers - presumably other family members as well. About 60 entries in all, including references to surnames: Ebert, Quirner, Lehman, Ketterer, Schmidt.
"Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950).

Indexing Milwaukee's German newspapers continuously since 2007 ... it's about German-American culture, not data.
