## Marriages and family
### Marriage to Prince Louis of Luxembourg

Antony met Prince Louis for the first time while he was a member of the army.
On 12 March 2006, Antony gave birth to a boy, christened Gabriel Michael Louis Ronny de Nassau, who was born at a private Swiss hospital, Clinic des Grangettes, in Geneva. The baby was the first grandchild for Grand Duke Henri and Grand Duchess Maria Teresa.
The couple married on 29 September 2006 at a parish church in Gilsdorf. Upon their marriage, Prince Louis gave up succession rights for himself and his descendants, but retained the title of Prince of Luxembourg and the style of Royal Highness. The couple's second son, Noah Etienne Guillaume Gabriel Matthias Xavier de Nassau, was born on 21 September 2007 at Grand Duchess Charlotte Maternity Hospital. The couple's sons were initially given the surname de Nassau with no titles.
On Luxembourg's National Day on 23 June 2009, a decree was issued granting Tessy the title of Princess of Luxembourg and Princess of Bourbon-Parma with the style Her Royal Highness. The same decree gave the title Prince of Nassau and style Royal Highness to her and Louis' sons Gabriel and Noah and possible future children. In 2012, Princess Tessy received the Order of Civil and Military Merit of Adolph of Nassau. The decree granting Tessy de Nassau the rank of Princess of Luxembourg was, however, unlike previous decrees conferring titles, not made transparent to the public.
On 18 January 2017, the Grand Ducal Court announced the separation of the Prince and Princess, and their intention to divorce, whereupon Princess Tessy lost her Grand Ducal titles. However, Articles 1 and 4 of the 1995 Grand Ducal Decree (as amended) state:
   Article 1. In the public and private acts which concern them, the Princes and Princesses born in the first degree of descent from the Sovereign shall bear the style of 'Royal Highness' before their given name and the surname '(de) Nassau' and shall bear the title of 'Prince or Princess of Luxembourg' following their given and surnames. Children of the heir presumptive shall be designated in the same manner... Article 4. In the event of separation of bed and board, of divorce or remarriage after spousal death, the titles enjoyed by consorts of the Princes of Our House in accordance with the present decree shall be lost forthwith.
The divorce proceedings occurred in London, and the divorce was finalized on 4 April 2019.
