Meet The Royals Who Are In Line For The Throne In Luxembourg

Prince Guillaume Jean Joseph Marie of Luxembourg, commonly known as Prince Guillaume, is a prominent member of the Grand Ducal Family and next in line for the throne. He was born on November 11, 1981, and is the son of Henri and his wife, Grand Duchess Maria Teresa. Guillaume officially took the title of Hereditary Grand Duke on October 7, 2000.

Guillaume's education and career are quite distinguished. He studied at the University of Angers in France, where he completed double degrees in Literature and Political Science with honors. Later, he held internships at prestigious companies including Deutsche Bank in London, the Spanish ArcelorMittal steel group, and with the Belgian Chemical Union.  Guillaume attended the Royal Military Academy Sandhurst in Great Britain in the early 2000s to complete officer training and he is a Colonel in the Luxembourg army. He has been actively involved in various charitable and cultural organizations over the years reflecting the royal family's commitment to public, and his cultural service and humanitarian endeavors include working on a reforestation project, assisting disadvantaged peoples, and serving as the Chief Scout of Scouting in Luxembourg.

Guillaume married Countess Stéphanie de Lannoy, a Belgian noblewoman, on October 20, 2012. The couple's wedding was a grand event — one of the largest in decades — attended by numerous European royals such as Felipe of Spain, the Earl and Countess of Wessex, and the King and Queen of Greece.

Prince François Henri Luis Marie Guillaume, born on March 27, 2023, is Guillaume and Stéphanie's second child, and he weighed 7.88 lbs (3.575 kg) at birth. He is third in line for the throne after his older brother Charles. 

François was born at Maternité Grande-Duchesse Charlotte in Luxembourg, and he was anxiously awaited by his family. "We are always incredibly happy about an addition to our family," Guillaume expressed to RTL when the news of Stéphanie's pregnancy was announced (via Hola!). To welcome him to the world, François was given a 21-gun salute at the Fetschenhaff, and citizens of Luxembourg were able to offer their congratulations via a book posted at the guardhouse. Guillaume and Stéphanie also asked those inclined to give donations to the Fondation Lëtzebuerger Kannerduerf (also called SOS Children's Village Luxembourg.) The program helps at-risk youth become independent adults. 

Princess Amalia of Nassau was born in 2014 at Grand Duchess Charlotte Maternity Hospital in Luxembourg, and she is the oldest child of Prince Félix and Princess Claire. Amalia is the first granddaughter of Henri and Maria-Teresa, and she is 5th in line for the throne. 

 According to the country's bylaws, only those in the direct line are styled as Prince or Princess of Luxembourg. As a child of Félix, the younger son of the Grand Duke, Amelia is not a Princess of Luxembourg but is Princess of Nassau instead  — "zu Nassau" is the family name of the descendants of Grand Duchess Charlotte (1896-1985.) She could also use the title Princess of Bourbon-Parma due to being a descendant of Prince Felix of Bourbon-Parma (Charlotte's husband). This rule went into place in 2012 which means there are a few members of the royal family not in the direct line of the Grand Duke that are styled as Prince/Princess of Luxembourg. 

Princess Alexandra Joséphine Teresa Charlotte Marie Wilhelmine, born on February 16, 1991, is the 4th child of Henri and Maria Teresa and is their only daughter. She holds the titles Princess of Luxembourg and Princess of Nassau and Bourbon-Parma and is 7th in line for the throne.

Alexandra's education includes schools in Luxembourg and abroad. She received a Baccalaureate in Arts and Literature from Lycée Vauban in 2009. She also studied in the U.S. and Paris, before earning a Master's degree in Interfaith Studies from the Irish School of Ecumenics. She did an internship with the Security Council of the United Nations in New York, and is fluent in Luxembourgish, French, English, and Spanish (she also speaks passable German and Italian.) Alexandra volunteers with refugees, was awarded the noblest distinction of The Order of the Gold Lion of the House of Nassau, and patronages the Luxembourg Association of the Blind.

In 2023, Alexandra wed Nicolas Bagory, a French businessman in a civil ceremony on April 22. They also had a religious wedding on April 29, 2023 which took place at Saint Trophyme church in the South of France. She donned the famous Chaumet Choker Tiara a family piece which has been worn by her mother as well as her grandmother Grand Duchess Joséphine-Charlotte.

Prince Guillaume Marie Louis Christian, born on May 1, 1963, is the third son and youngest child of Grand Duke Jean of Luxembourg and Grand Duchess Joséphine-Charlotte. He is ninth in line for the throne even though his brother Prince Jean is older than him. However, Jean renounced his throne rights in 1986 — his heirs are also not eligible, thus skipping his line in the succession.

Guillaume attended school in Luxembourg, Switzerland, and the United Kingdom before obtaining his degree from Georgetown University in Washington, D.C. His career has included time working at the International Monetary Fund, the Commission of the European Communities, and ArcelorMittal.

He wed Sibilla Sandra Weiller (now Princess Sibilla of Luxembourg) in 1994, and they have four children. In September of 2000, they were rear-ended by another car while driving near Paris. Sibilla required surgery for a broken leg, and Guillaume incurred a severe head injury that left him in a coma for three weeks. Both recovered well and are integral members of the royal family — they both perform duties such as meeting with ambassadors and attending charity events.

Prince Léopold Guillaume Marie Joseph was born on May 2, 2000, in Luxembourg City, Luxembourg. Léopold is the third child and second son of Guillaume and Sibilla — he is 11th in line for the throne after his brother Paul-Louis. 

Léopold is among the younger generation of Luxembourg royals and thus not as busy with public events as his parents, uncles, and cousins. He did attend the wedding of his cousin Crown Prince Guillaume to Stéphanie in 2012 with the rest of his family. He also attended the Le Bal des Débutantes in 2018 with his twin sister Princess Charlotte, and then attended again the year after with Princess Maria Carolina of Bourbon Two Sicilies. In 2020, Léopold was in Belgium where he attended a car-free day with Queen Mathilde and King Philippe of Belgium. He was reportedly staying with the royal couple while studying in their country.

Prince Robert Louis François Marie of Luxembourg, born on August 14, 1968, is the son of Prince Charles of Luxembourg, the second son of Charlotte and Felix, and Joan Dillon, the American daughter of former U.S. Treasury Secretary C. Douglas Dillon. He is 13th in line for the throne.

Robert's education included boarding school at Worth Abbey in Sussex and studying philosophy and psychology at Georgetown University in Washington, DC. He didn't graduate from Georgetown, however, as he dropped out to travel the world. "I was a young man without responsibility, constraints or family commitments — a total idealist starting out on life," Robert told Club Oenologique in 2021. He is the president of a French wine company started by his mother's family called Domaine Clarence Dillon.

He married Julie Elizabeth Houston Ongaro in 1994. Princess Julie is the daughter of Harvard professor Dr. Theodor Ongaro and Katherine Houston, an artist. Julie and Robert have three children: Princess Charlotte, Prince Alexandre, and Prince Frederik. Originally, Robert's wife and children did not have Prince/Princess stylings since his marriage was unsanctioned, but Duke Henri upgraded their titles in 2004.
