Have you collected the family death notices for Michael Staab and Anna Maria Barbara Staab (referencing Trunk) from Milwaukee's German newspapers? I've indexed them in "Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950). These notices are fairly rare as the custom for the family to publish these notices was not too common in the 1880s. There are about 50 entries for Staab in the growing data and other surnames connected with Staab include: Bruhn Cordes Dressler Drossler Senft Mueller Trunk
