Victoire de Noailles
The Noailles family first rose to prominence with Antoine, 1st comte de Noailles, who was French Ambassador in England 1553–1556. The family reached its peak under Adrien Maurice de Noailles, 3rd Duc de Noailles, Marshal of France and his brother the Cardinal-Archbishop of France. The 3rd Duke's father and two of his sons were also Marshals of France. Today, there are two ducal branches – the ducs de Noailles and their cousins the ducs de Mouchy, represented by their head the 7th Duc de Mouchy (subject of this biography).
Philippe, Duc de Mouchy, is descended from a marshal of France Philippe Cte de Noailles (27 December 1715-guillotined at Paris 27 June 1794) who was the 5th child (of six children) and second (and younger) son of Adrien-Maurice de Noailles, 3rd Duc de Noailles, etc. (29 September 1678 – 24 June 1766), also a marshal of France.
The first Duc de Mouchy was created Prince de Poix 1729 aged 14 and Duc de Mouchy 1749 aged 34 in Spain, and was also granted the French title of duc de Poix à brevêt in 1767. The first Duc de Poix and his Duchesse were both guillotined 27 June 1794 at Paris, during the Reign of Terror.
The 1st Duc de Poix was succeeded by his fourth but first surviving son :Philippe Louis Marc Antoine, 1st Duc de Mouchy, 2nd Duc de Poix et de Mouchy, cr 1st Duc de Mouchy 1817 (21 December 1752 – 15 February 1819), first surviving son of the Duc de Poix styled Duc de Mouchy after his Spanish title (d. 1794) and grandson of the 3rd Duc de Noailles. The 1st Duc was succeeded by his two sons in succession. The second son was :
Antoine Claude Dominique Just, 3rd Duc de Mouchy, 4th Pr-Duc de Poix, Cte de l'Empire 1810 (25 August 1777 – 1 August 1846) who married a relative of Talleyrand and had issue including :
Charles Philippe Henri, 4th Duc de Mouchy, 5th Pr-Duc de Poix (Paris 9 September 1808 – Paris 25 November 1854), father of :
Antoine Just Léon Marie 5th Duc de Mouchy, 6th Pr-Duc de Poix (Paris 19 April 1841 – Paris 2 February 1909), grandfather of :
Henry Antoine Marie, 6th Duc de Mouchy, 7th Pr-Duc de Poix (Paris 9 April 1890 – Paris 1 November 1947), father of :
Philippe François Armand Marie 7th Duc de Mouchy, 8th Pr-Duc de Poix (Paris 17 April 1922 – February 2011). The Mouchy dukedom here is French (he also possesses the Spanish dukedom of that name created in 1749).
The Duc de Mouchy was cousin to HH Princess Yolande de Ligne, wife of Archduke Karl Ludwig of Austria, fourth son of Karl I, last Emperor of Austria and King of Hungary; and to her brother HH Antoine, 14th Prince de Ligne, married to HRH Princess Alix of Luxembourg, aunt of the present Grand Duke of Luxembourg.
His daughter-in-law is HRH Princess Diane d'Orleans, daughter of Jacques Duc d'Orleans and of the duchess, born Gersende de Sabran-Pontevès, herself a daughter of the Duc et Duchesse de Sabran-Pontevès. As a result of this marriage to his younger son, Alexis, the Mouchy family is related to the Orleans pretenders to the French throne. The current title holder is Henri, HRH the count of Paris, Duc de France, uncle of Diane.
