You are very welcome for the information.
The Letzeburgesch dialect is quite far removed from high German, however, and often Germans cannot understand it at all. However, the Germans living around Bitburg, just north of Trier in the western part of the Rheinland do understand it and still speak it in their homes. In fact, prior to 1815, the District of Bitburg belonged to the Grand Duchy of Luxembourg!
I have a genealogy friend with 100% Luxembourg ancestry, whose ancestors came to central Minnesota beteween about 1860-1870. The older generation still speaks Letzeburgesh among themselves. My friend’s mother went on a trip to Germany,and when she returned, she told her daughter, “I could not understand most of the Germans at all, until I came to Trier where I could speak my “German” and they understood me.”
Very interesting. We spent 8 years in Germany, 4 at Zweibrucken AB, and 4 in Berlin. I knew there were many dialects of German but to tell the truth, my German was so poor it was hard to distinguish between them. I do remember that the Berliners talked very fast.
