Does someone can identify the bride & groom on this photo?

I can recognize some of the royal guests: Queen Giovanna of the Bulgarians, Prince Louis Ferdinand & Princess Kira of Prussia, Crown Princess Beatrix and Princess Margriet of the Netherlands, Crown Prince Vittorio Emanuele of Italy, Princess Viktoria Luise, Duchess of Brunswick and Prince Georg Wilhelm of Hanover... Maybe due to the Italian and Bulgarian presence I'd say it's a Hessian occasion.
