There are over 50 Stowasser entries in "Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950). These include death notices published by the family for Anton (Sr.), Margaretha, and entries for their children, like 6 yr. old Anton Jr.
There are a few references to Reinl, but also spellings of Reinel in the current data.
