"looking for Katie Schneider who married Henry Schuler or Schueler around Milwaukee WI ..."

Do you have a date range on these Schuler/Schueler/Schneider names?
There potential matches (depending on they lived ;-) found in "Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950).
