Karen -- The death notice for the Margarethe Vogel I referenced matches the one in your posting and the entry found at the Milwaukee Archdiocese' cemeteries site. Of course, I have no idea if she's your relative. I can tell from my index entry that the family did not include family detail.
By the way, the Michael Planer from your original posting has death notices referencing Margaretha (Vogl) and an obit. that may be either brief or detailed.
You're in the Milwaukee area so have easy access to the outdated printed indexes. If you'd like assistance collecting & translating these clippings contact me directly. I only provide citations with translations.
