What started me on the search is that I thought I saw the name in Iowa or by the Warnecke family in the Faribault county in Minnesota. When I went back to find it, I couldn't.
I had seen it on two passenger listings. Once it was misspelled KONAN and on another source copies of the passenger lists , it was correctly related as KONAU. We have been discussing the passenger list of 1883.
I looked again in census and there does seem to be very few there. At least not where I though I saw it before.
If I see it again on one of the census that I wanted you to see, I will come back and edit it in.
Here is the data where the name Konau appeared in my correspondence with the church volunteer. He gave me this record. Remember now, that we have this Meyer at Sammatz and Luhmann family lived there. You can click here and the title for the link where this is discussed.
