Széchényi’s elder brother spent a significant part of his life in Vienna, where he held court as the chief court master to Archduchess Zsófia – Franz Joseph’s mother. He is remembered as a composer of high artistic quality and as an active and important figure in the institutionalisation of Viennese music. He married twice, both times from a family of the ‘supranational’ imperial aristocracy: He was married to Alojzia Clam-Gallas, then Countess Franciska Wurmbrandt. Of the 9 children born of the two marriages, 8 reached adulthood; several of them appear regularly in the letters.
