"My great-grandfather was Frank Imp, son of Theresa Feiler and John Imp. Theresa had several children with someone with the surname of Ebenspenger first, then married John Imp ..."
John Imp & Theresa Feiler Imp's death notices were published in Milwaukee's German newspapers (1936 & 1940). I don't know if they are identical to what might be found in the English language papers of that era. These are the only two entries I've indexed in "Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950).
