In case it's helpful to anyone's Ewald research, Augusta Luedtke Stark Ewald's death notices are found in the local German newspapers. There are also death notices for an August Ewald in 1924. Emilie Ewald Otto's death notices were published in these papers, and there several different Carl/Karl Otto's to choose from (depending on when he died ;-)
These are some of the approx. 75 Ewald and almost 400 Otto entries or references found in the library resource "Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950). These newspapers and the index are not online. The library version is sadly out-of-date 8-(
