You may have collected them already, but I've indexed multiple family death notices and an obit. w/photo for your Katherine Ott, née Boehm. These are some of the 300 entries or references from the local German papers collected in "Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950).
"... Becker, Bittner, Boehm, Bolker, Hoppe, Klienschmidt, Kraus, Linger, Meerschaert, Michels, Ott, Schottler, Schramm, Shubert, Tiegs, Wendte; and the following Polish-German names: Czyaplewski, Garski, Geyso, Hilkoske (Hills), Jurska, Kujath, Lazinski, Nowak, Rogowski (Rogers), Visniskie, Wisniewski (Wise) and Witkowski ..."
There are about 175 entries or references to either Boehm or Böhm -- be sure to check both spellings in any of Milwaukee's record collections!
Most, if not all of the Germanic surnames you've listed, and some of those Polish names are also found in the growing index.
