Early life

Guy Louis Jules de Lasteyrie du Saillant was born on 3 October 1879. From birth until his father died in 1923, he was referred to as "Count" Guy de Lasteyrie, as it was customary to address the eldest son of a marquis as "Count." His family had a home in Paris and in the French countryside, known as the Château de la Grange-Bléneau.

Through his father's family, Guy was a great-great-grandson of American Revolutionary War hero Gilbert du Motier, Marquis de Lafayette, through his youngest daughter, Marie Antoinette Virginie du Motier, who married Louis de Lasteyrie, Marquis de Lasteyrie, and had four children. Their son, and Guy de Lasteyrie's grandfather, was Adrien Jules de Lasteyrie, who married Olivia de Rohan-Chabot (a daughter of the émigré Louis de Rohan, Vicomte de Chabot, and Lady Charlotte Fitzgerald).

In 1923, he officially became the Marquis de Lasteyrie du Saillant upon his father's death. His third cousin was Charles de Lasteyrie.

Personal life On December 19, 1912, Guy was married to sculptor Constance Whitney Warren at St. Patrick's Cathedral in New York City. Constance, who shared his love of horses, was from a large and prominent American family. She was the only daughter of George Henry Warren II, a granddaughter of George Henry Warren, cousin of Robert Walton Goelet and Edith, Lady Queensborough, and niece of Whitney Warren and Lloyd Warren, prominent architects. After their marriage, they lived in an apartment in Paris and at the Château de la Grange, located outside Paris. Guy and Constance were divorced in either 1920 or 1922.

In 1934, Guy and his brother, Louis de Lasteyrie, sold the Château de la Grange-Bléneau to their cousin, René de Chambrun, with a life tenancy.

Guy died on 14 August 1944.
