Hello! I´m finding myself deep interested on count, later prince, Andrei Razumovsky. As far as I know, he was son of Kyrill Grigorievich Razumovsky, young brother of Alexey Grigorievich Razumovsky, the favourite and maybe secret husband of Elizabeth Petrovna, called the Night Emperor.
Andrei Razumovsky was a great diplomat who spent a lot of years of his life in Vienna. Extremely healthy and sophisticated, he loved music very much. He introduces Haydn music in russian court, and also was a patron both to Wolfgang Amadeus Mozart and Ludwig van Beethoven. Circa 1788, he was married to countess Elisabeth von Thun Hohenstein. She was daughter of Maria Wilhelmine, born gräffin von Ulfeld, by marriage gräffin von Thun Hohenstein; and the older sister of Elisabeth, Christiane, was married to prince Karl Lichnowsky. Well...Maria Wilhelmine was a patroness of Mozart, as Karl and Christiane Lichnowsky was patrons of Beethoven a few years later. The younger sister of both Elisabeth and Christiane, Caroline, was married to Robert Meade, second earl Clamwilliam, and Caroline´s son, Richard Meade, lord Clamwilliam, played a role while the Congress of Vienna as a young diplomat attached to Lord Castlereagh.
Razumovsky himself had a sad storie to tell about the Congress. He had built, at his own expense, a magnificient neoclassic palace, an embassy representative of Alexander I´s power. On New Year´s Eve 1814, Razumovsky offered a great ball, and, to do this, he ordered to erect a temporary ballroom extension heated by a flue from the palace. After all the guest are gone (probably the only one who was invited but refused to go was Beethoven...), the flue caught fire and the palace burned.
I just have found this portrait of count Andrei and no portrait of his beautiful austrian woman Elisabeth:
