Joan de Noailles, Dowager Duchess of Mouchy and Poix (née Joan Douglas Dillon; born 31 January 1935)[1] is an American-born French duchess, the first commoner to marry into the reigning dynasty of Luxembourg, and is the former president of French Bordeaux wine company Domaine Clarence Dillon.


Joan Dillon is the daughter of U.S. Treasury Secretary C. Douglas Dillon and his wife, Phyllis Chess Ellsworth.[1] She came to live in Paris, France, with her family when her father was appointed American Ambassador in the 1950s. She initially found work with the Paris Review.[2]

After her marriage to Prince Charles of Luxembourg she discovered an interest in wine and the family interest in Haut-Brion.[2] From 1975 to 2008, Joan Dillon held the presidency of Domaine Clarence Dillon.[3] Her husband, Philippe de Noailles, Duc de Mouchy, was general manager. Under their direction the company bought Château La Mission Haut-Brion, Château Laville Haut-Brion and Château La Tour Haut-Brion in 1983. In 2008 Prince Robert of Luxembourg, her son by her marriage to Prince Charles of Luxembourg, became president of Domaine Clarence Dillon.

Wine Enthusiast Magazine describes Dillon as "a larger-than-life lady, with an indefinable, cultured, mid-Atlantic accent."[2]


She married firstly in Paris, France on 1 August 1953 James Brady Moseley (New York City, US 22 May 1931 – Boston, Massachusetts, US 9 April 1998), son of Boston investment banker Frederick S. Moseley, Jr. and his wife, Jane H. Brady. The couple divorced in Washoe County, Nevada, US on 12 December 1955; the marriage was annulled in Rome, Italy on 22 June 1963.[1] They had a daughter,

She married secondly on 1 March 1967 Prince Charles of Luxembourg (younger son of Charlotte, Grand Duchess of Luxembourg) at the Catholic Church of St. Edward the Confessor in Sutton Park, Surrey, UK. The marriage was the first authorized of a Luxembourgeois prince to a commoner – authorized by Grand Ducal decree issued 16 February 1967. She was styled "HRH Princess Joan of Luxembourg".[1] Prince Charles died in Imbarcati, Province of Pistoia, Italy, on 26 July 1977. They had two children:

  • Princess Charlotte of Luxembourg (born New York City, 1967), married civilly in Mouchy, France on 26 June 1993 and religiously in Saint-Rémy-de-Provence, France on 18 September 1993 Marc-Victor Cunningham (born Harrogate, 24 September 1965), son of Victor Cunningham and wife Karen Armitage.[1]
  • Prince Robert of Luxembourg (born Fischbach Castle, Luxembourg, 1968), married non-dynastically (although his wife and three children would be elevated from countly rank to princely dignity 26 January 2004, they were subsequently re-titled as Counts and Countesses de Nassau[citation needed]) in Boston, 1994 to Julie Elizabeth Houston Ongaro (born Louisville, Kentucky, US, 1966),[1] daughter of urologist and Harvard University professor Dr. Theodore Ongaro and wife Katherine Houston.[1]
