Milwaukeean Baroness Emma Deuster von Paumgartten's obituary (d. Toronto, Can., 1948) was published in the last locally published German language daily in Milwaukee. It references her children and siblings (Hansen). She was the daughter of Peter Victor Deuster & Gertrud Stolz Deuster and married Baron Peter von Paumgartten.
Peter Victor Deuster was long-time publisher of the "Milwaukee Seebote" newspaper (various versions of that name: Milwaukee See-Bote, etc.).
There are just a handful of Starkweather entries or references found in "Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950). But none of them appear to be German royalty.
