About Madame de Saint-Laurent
Lived 1760 – 1830 (aged 69–70). Madame de Saint-Laurent was a French.
Alphonsine-Thérèse-Bernardine-Julie de Montgenêt de Saint-Laurent (30 September 1760 – 8 August 1830), often known as Julie de Saint-Laurent or Madame de Saint-Laurent, was a French baroness who was for almost 30 years the partner of Prince Edward, Duke of Kent and Strathearn.
Life Julie de Saint-Laurent was born on 30 September 1760 in Besançon, France, to Jean-Claude Mongenêt, a civil engineer, and Jeanne-Claude (Claudine) Pussot.
Marriage She married Jean Charles Andre de Mestre, Baron de Fortisson, a colonel in the French service.
During the French revolution, the couple along with their infant daughter Melanie fled to the safety of Geneva. has established that no children were born of the 27-year relationship between Prince Edward and Julie de Saint-Laurent; although many Canadian families and individuals (including the Nova Scotian soldier Sir William Fenwick Williams, 1st Baronet) have claimed descent from them, such claims can now be discounted in light of this new research.
For twenty-eight years Saint-Laurent presided over the Duke's household, as a local chronicler records, "with dignity and propriety". She is described as having been beautiful, clever, witty and accomplished. Many of her letters will be found in Anderson's The Life of Edward, Duke of Kent (Quebec: 1870). After the Duke's marriage in 1818 to the Dowager Princess of Leiningen, Saint-Laurent retreated to Paris where she lived out her days amongst her family and friends.
She died in 1830 and was buried with her sister, Jeanne-Beatrix, Comtesse de Jansac, at Père Lachaise Cemetery in Paris.
Legacy She has given her name to two roads and a pond in the neighborhood of Prince's Lodge in Bedford, Nova Scotia:
Julie's Pond or The Heart Shaped Pond - a man-made body of water built on order by Prince Edward at the foot of Kent Road in what is now Hemlock Ravine Park St. Laurent Place - short residential road in Prince's Lodge, Nova Scotia Julie's Walk, Bedford - short residential road in Prince's Lodge, Nova Scotia
