There is an obit of some sort for a Josephine Lackner Best in Milwaukee's German newspapers (but of course, she died in Osthofen, Hessen-Darmstadt). And in case it's a match for your entry for her son Emil, there are death notices for an Emil Best in 1916. These are some of the 200+ Best clippings indexed in "Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950).
