It seems that there is no rule on how to use the names of cities, mountains and valleys of the world, even with languages as close as German and English. We all say “New York” and “Chesapeake Bay”, but on the other hand we rather say “Themse” than “Thames”. In the Internet, you find the German name “Siebengebirge” as well as the English version “Seven Mountains”. The mountains, actually they are hills, are known by their German name. Nonetheless, it might interest you what they mean.
