In case this helps with your research, a John Lepak, a milk man, died in Milwaukee in Nov. 1874, and then his mother in the same week. There was an inquest for John, maybe for his mother, and clippings may show up in a search at the subscription site "19th Century U. S. Newspapers" (available to use through some libraries like the public library in Milwaukee). The may be an inquest file for him at the Milwaukee County Historical Society Library.
I've indexed the clipping about John Lepak and his mother found in the local German newspapers in "Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950).
