Past Life & Family
Tessy Antony De Nassau met her ex husband HRH Prince Louis for the first time in the military after her return from deployment.
On 12 March 2006, she gave birth to a boy, christened Gabriel Michael Louis Ronny Antony later named 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. The couple’s second son, Noah Etienne Guillaume Gabriel Matthias Xavier de Nassau, was born in 21 September 2007 at Grand Duchess Charlotte Maternity Hospital. The couple’s sons were initially given the surname de Nassau with no titles. Sometime after the birth of Noah, Tessy had a third pregnancy which ended in a miscarriage. She has called it “one of the most difficult situations I have ever faced.”
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 two sons Gabriel and Noah.
The couple finalised their divorce after 12 years of marriage in 2019.
