Hi. I don't know if either of you ever found an answer. Here's a couple of websites with lists that might help. Is the "K" for "Katholisch" (Catholic) I wonder? The German words for directions are Nord, Sud, Ost, und West (you can kind of figure out what they mean). Is the "K" actually an "R" perhaps? If you really have "NRW", it would be an abbreviation for "Nordrhein-Westfalen" or the area of North Rhine-Westphalia.

Here's some links that might help:
