Early lifeEdit

Princess Stéphanie of Luxembourg was born on 18 February 1984 in Ronse, East Flanders. She is the youngest daughter of Count Philippe de Lannoy and Countess Alix della Faille de Leverghem (1941-2012). She has seven siblings. She grew up on the family estate, the Château d'Anvaing.

The House of Lannoy has been traced back to the 13th century nobility of Hainaut, its members distinguishing themselves in military command and affairs of state. Those descended from Charles de Lannoy, the victor of Pavia held the Imperial title of count/countess from 1526. Stéphanie descends, through the cadet branch of the lords of Motterie, from the earliest known member of the family, Baudouin de Laval, who died c. 1301, having flourished at Lille. Since the beginning of the 19th century her ancestors have usually also been burgomasters of Anvaing. Stéphanie's paternal grandmother, née Princess Beatrice de Ligne (1898-1982), was a daughter of Ernest, 10th Prince de Ligne, head of one of Belgium's most historically powerful families. Stéphanie's maternal grandparents, Harold della Faille de Leverghem and Madeleine de Brouchoven de Bergeyck, were also members of Belgium's titled nobility belonging, respectively, to a baronial and to a comital family.

Stéphanie attended the Dutch-language Sancta Maria de Ronse school, and later moved to France to continue her education in Collège Saint-Odile. She then returned to Brussels for studies at L'Institut de la Vierge Fidèle.

She moved to Moscow where she studied Russian language and literature. She majored in German philology at Louvain-la-Neuve and also earned a master's degree in Berlin. During her master's program, she interned at L'Agence wallonne à l'Exportation in Berlin.

She speaks French, Dutch, English, German and Russian. She is interested in music, foreign languages and sports such as swimming or skiing.
