:::: You cannot have it both ways: the head of princely house can grant one a title but not a coat of arms?! Either such a prince can grant both or none of the two. By your argument, with Germany being a Republic, the Furst von Hohenzollern cannot grant either titles or coats of arms.  

 Besides, Radu Duda was granted a "name," not a "title." Read again the urkunde and its translation if you have any doubts. Your edit to the article was erroneous, which I corrected, as Duda was not granted a "title", only a "name".
