Thank you for the suggestion, Thomas. I don't think I will take it up, though. I don't doubt HH Rainer Prince of Hesse is a very charming man, as you say, but it is only natural that he should be none too keen on sharing such information on the relationship between his parents and the era of WWII, insofar such knowledge is not in the 'public domain' yet. I'd better see whether the questions I have are answered in Prince Wolfgang's autobiography, as Marlene suggested.
