Dear Dean.
I am a grandson of Johann Wilking. He was married to Henny, nee Kuhlmann and had two daughters, Ingeborg (my mother) and Herta. Johann grew up in Bloherfelde and later became a well-connected businessman, Kolonialwaren Johann Wilking (food wholesale) in Donnerschweer Str. Johann had a business partner, known as uncle Simon. As a staunch opponent of the Nazis, Johann sent Simon (Jewish) to the States before it was to late and kept his share safe for his return after the Nazi-spook. There were connections to Brazil and to the US as far as I remember. There was Ella Wilking and her son Dieter, who emigrated to the States. My mother was close to Inge Lehmkuhl, related to the Wilkings, and was the godmother of her son Rolf. The Lehmkuhls ran a Construction Company (Baugeschaeft) in Bloherfelde. I hope, this information can help you.
kind Regards.
