Hello Rod,
Here are 1940-44 maps of Germany, 1 : 100,000 scale, that will surely show the location you are looking for. Krefeld is Map #378, I believe. Be patient. It takes forever and a month of Sundays to download these map sheets. From your additional information, it sounds like it's in the Viersen-Neersen-Willich area. I could not find your location on Google Earth or the Deutsche General Karte, 1 : 50,000 scale published in the late 1950's, so it must have changed its name right after the war.
