Louis Joseph d'Albert, 3rd Prince of Grimberghen

Louis Joseph d'Albert, 3rd Prince of Grimberghen (1 April 1672 – 8 November 1758) was a French nobleman who was in the service of the Emperor Charles VII, and became field-marshal and Ambassador in France.

His siblings included Marie Anne d'Albert de Luynes (wife of their second cousin, Charles III, Prince of Guéméné),[1] Marie Charlotte Victoire d'Albert de Luynes (wife of Alexandre Albert François Bathélemy, 4th Duke and 2nd Prince of Bournonville),[2] Catherine Angélique d'Albert de Luynes (wife of Charles Antoine II Gouffier, Marquis of Heilly),[3] and Jeanne Baptiste d'Albert de Luynes (the wife of Giuseppe Ignazio Scaglia, Conte di Verua and mistress of King Victor Amadeus II of Sardinia).

[5] From his father's first marriage to Louise Marie Séguier, Marquise of O, his much older half-brother was Charles Honoré d'Albert, 3rd Duke of Luynes.

After Claude's death in 1655, the Chevreuse peerage became extinct after which his grandmother bought the duchy which his father and younger brother Charles-Hercule d'Albert de Luynes inherited.

His wife's elder brother was Alphonse, 2nd Prince of Grimberghen, a Grandee of Spain who married Anne Henriette Rohan-Chabot (a daughter of Louis, Duke of Rohan).
