"... Joh. Friedrich Hempe who came to Wisconsin from Silesia, Prussia, in the early 1850s, with his second wife, Helena Stolper, and three children, Carl, Gottfried and Anna ... They lived in Milwaukee County, WI."
There are about 35 entries or references to the Hempe name in "Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950). These include the fairly early death notices that the family published for both Friedrich and Helene Stolpe Hempe. Did daughter Anna marry John Glade? Some of the other surnames I've referenced with Hempe include Baumann Heinrich Riedel Berger Neumann.
