The Grand Duke attended the funeral of his uncle Prince Alexander of Belgium today in Laeken. His sisters Princess Margaretha and Princess Marie-Astrid also attended. Princess Marie-Astrid was accompanied by her husband Archduke Carl-Christian and his mother Archduchess Yolande (nee de Ligne).
Belga and PPE Agency each have a gallery of photos of the funeral.
King Albert II of the Belgians is now the only remaining biological uncle of The Grand Duke and his siblings. Their uncles King Baudouin of the Belgians and Prince Charles of Luxembourg died in 1993 and 1977, respectively. They have 5 surviving biological aunts. The surviving sisters of Grand Duke Jean are Princess Elisabeth, Princess Alix, and Princess Marie-Gabriele. Princess Marie-Adelaide predeceased them in 2007. Grand Duchess Josephine-Charlotte was survived by her younger (half) sisters Princess Marie-Christine and Princess Marie-Esmeralda.
I extend my deepest sympathy to the family of Prince Alexander. Despite being relatively unknown, he was one of my favorite princes and I am saddened by his sudden death.
