There are about 65 entries for Rutz and over 75 Ruehl & Ruehle entries found in "Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950). This is a new resource since your posting in 2005.
Information on families from Milwaukee's rural townships is more rare than for city families, but it depends on the individual family as to whether they used the German papers for publishing death notices or were known in business circles in the city.
Verification of names with dates are offered via email because the index and the newspapers are not available online.
