I cannot find a Nellie Haffelder in a quick search of my things. Do you have any information on where in Germany or where in Wisconsin? I know they were in the New Berlin area and then up to Menomonee and that they came from Neckarbishofshein, Germany. I will tell you this, I had a feeling the Haffelders in Texas were connected, and sure enough, I kept searching and found the connection. I believe any that spent time in Wisconsin are surely connected. I will try to look into it further when I get a chance.
