After a series of apparent delays, the Duke and Princess Olga finally wed on 16 September 2008, at the Italian embassy in Moscow. They have three children: Prince Umberto of Savoy-Aosta, the 15-year-old heir apparent to the Dukedom of Aosta; Prince Amedeo Michele, Duke of Abruzzi, born on 24 May 2011; and Princess Isabella Vita Marina, 12, who was named in honour of her great-grandmother, Princess Isabelle of Orléans.
