The Grand Ducal Family consists of the extended family of the reigning Grand Duke of Luxembourg. The current head of state of the world's only remaining Grand Duchy is Grand Duke Henri, who is also the head of the House of Nassau-Weilburg.


Grand Duke Adolphe, Grand Duke Guillaume IV and Grand Duchess Marie-Adélaïde 

The current Grand Duke is the sixth ruler of the House of Nassau-Weilburg, who inherited the claim to the Luxembourgish throne in 1890 when William III. King of the Netherlands and Grand Duke of Luxembourg died without leaving a male heir. The dispossessed Duke of Nassau Adolphe became the new Grand Duke. When Grand Duke Adolphe died in 1905 he was succeeded by his oldest son Grand Duke Guillaume IV.

Together with his wife Infanta Maria Ana of Portugal, Grand Duke Guillaume IV had six daughters. As there were no male dynastic heirs in 1906, the Grand Duke named his oldest daughter Marie-Adélaïde as heir to the grand ducal throne. She would eventually succeed her father and ruled Luxembourg for seven years. After the First World War, due to being highly unpopular as she was unjustly considered pro-German, Grand Duchess Marie-Adélaïde was forced to abdicate in favour of her sister Charlotte.


Grand Duchess Charlotte 

At the beginning of her reign Grand Duchess Charlotte was faced with a referendum about a new constitution in which the Luxembourgers could vote between (1) keeping Charlotte as Grand Duchess, (2) retaining the monarchy but replacing Charlotte with another member of the family, (3) retaining the monarchy but replacing the dynasty or (4) getting rid of the monarchy and declare Luxembourg a republic. With a majority of 77,8% the referendum was decided in favour of a continuation of the monarchy under Grand Duchess Charlotte.

Through the marriage of Grand Duchess Charlotte to Prince Félix of Bourbon-Parma, she elevated the status of her descendants from grand ducal highness to royal highness; all her male line descendants are styled as royal highnesses due to their Bourbon-Parma heritage, with the exception of the Grand Duke, Hereditary Grand Duke and their respective spouses. The reigning Grand Duke (or Grand Duchess) and the heir apparant were naturally styled as royal highness, even before Charlotte's marriage. For example, Grand Duchess Marie-Adélaïde was elevated to royal highness the same day she was named Hereditary Grand Duchess. Exiled during the Second World War, the Grand Duchess became a strong symbol for national unity, resistance and freedom.

Grand Duchess Charlotte and Prince Félix had six children: Prince Jean, Princess Elisabeth (married Duchess of Hohenberg), Princess Marie-Adélaïde (married Countess Henckel von Donnersmarck), Princess Marie-Gabrielle (married Countess Holstein til Ledreborg), Prince Charles and Princess Alix (married Princess of Ligne).


Grand Duke Jean

The oldest son Prince Jean was born on January 5th, 1920 at the Château de Berg. After receiving his educational training at schools in Luxembourg and the United Kingdom, he was named Hereditary Grand Duke upon reaching maturity.

In 1940, after the family had fled Luxembourg which was occupied by Nazi-Germany, he started to study Law and Political Science at the Universitè Laval in Quebec City, Canada, before joining the British Army in 1942. As captain of the Irish Guards in landed in the Normandy in June 1944 and took part in the Battle of Caen, the Liberation of Brussels and finally on September 10th, 1944 the Liberation of Luxembourg. Upon returning to the Grand Duchy both the Hereditary Grand Duke and his father Prince Félix were carried around on the shoulders of their citizens.

In 1953 Hereditary Grand Duke Jean married Princess Josephine-Charlotte of Belgium, daughter of King Leopold III of the Belgians and sister to Kings Baudoin and Albert II. Although it was an arranged marriage, it was on all accounts a happy one and the couple were blessed with five children.

While Sibilla is a Princess of Luxembourg, their children carry the title of Prince and Princess of Nassau with the style of Royal Highness. The three sons of Prince Guillaume are in line of the succession to the throne.

Hereditary Grand Duke Jean succeeded his mother on the Luxembourgish throne upon her abdictation in 1964 and reigned until 2000. After Grand Duchess Josephine-Charlotte died after losing a battle with lung cancer in 2005, the former Grand Duke now lives quietly at the Château de Fischbach. At the age of 92, he still occasionally carries out official engagements.

Grand Duke Jean's deceased brother Prince Charles married the American born divorcee Joan Douglas Dillon in 1967 while she was pregnant with their first child. Princess Charlotte was born a few months after her parents wedding, her younger brother Prince Robert a year later. Prince Charles was also the step-father to Princess Joan's daughter from her previous marriage. Prince Charles died in 1977 because of heart failure. His widow later remarried the late Philippe de Noailles, the Duc de Mouchy (Prince-Duc de Poix). During her marriage to Prince Charles and her widowhood, Joan enjoyed the style of Royal Highness and the title Princess of Luxembourg. She currently uses combination of her maiden name and marital title: Joan Dillon, Duchess de Mouchy.
