On the city directories at Ancestry.com, I performed the search as shown on the screen--Cawiezell as the last name, unexact, living in Davenport, Iowa. There were seven matches, some of which are shown in the image. None were for the last name of Cawiezell.
When browsing manually Stone's 1888-1889 Davenport, Iowa, directory, I located the following entry for several Cawiezells, all living with Maria at 1019 W. 8th Street. I am assuming that Josephine is not the kind of stripper that might first enter someone's mind.
It is always a good idea to search the directories manually if you think the family lived there and they are not in the search results. In fact, there should be Cawiezell entries in every directory from ca. 1855 for Davenport. So I'll have to keep looking.
My wife descends from the Cawiezells.
