According to anecdotal tales there is another trait that Harry has that isn't quite normal to the Windsors and it's a bit more personal..and rather..err
large !.
It's also made him very popular with the young gels and lasses.
But you are wrong about
all the others..if you look at Andrew when he was younger he still had a good head of hair for far longer than his brothers and was more portly and stocky unlike his siblings and in fact had a much more jolly type of personality.
These of course are all just silly rumours that anyone in the Royal Family would have realtions outside marriage !
