There are about 40 occurrences of the Moldenhauer Moldenauer name culled from local German language newspapers and collected in "Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950). These include Pastor Samuel Moldenhauer and possibly others from your posting. There are also about 150 Hensel entries or references but I don't find any direct Moldenhauer connections referenced in the index. Some other related surnames are Potratz Sutzmer Maske Lewin.
Any index entries for members of the "Old Lutheran" immigrant community are integrated in the index with Milwaukee's diverse community of German Jews, German Catholics, and the rest of the German Protestant community found in these newspapers. It's an excellent collection for family firstname.lastname@example.org
