OK so while doing research on the German reigning houses I came across something confusing. Most sources I read call the non-reigning dynasts, like Rupert of the Rhine or August of Saxony, Princes but others give them titles like Count Palatine or Duke. Basically I'm trying to find out what the proper courtesy titles were for the top dynasties, like the Wittelsbachs of Bavaria and the Palatinate, the Welfs of Brunswick and Hanover or the Wettins of Saxony. Any help would be much appreciated!
