Good tip! There are also Manzke entries - Mrs. Albert (1951) & August (1907) - found in "Milwaukee's German Newspapers; an index of death notices and related items".
One of the challenges of using an index of German-American papers is the variety of spellings - even within the same article or notice. That includes names spelled with or without the umlaut. I've made the public version of the index available by name and by date -- so a couple of days worth of entries can be browsed to pick up variations.
