Between 1815 and 1822 he and his older brother Prince Achille Murat received a solid education at Schloss Frohsdorf in the Austrian Empire.

He later went to Venice, where he was pursued by the Austrian authorities, necessitating his departure to the United States where his elder brother Prince Achille Murat had already moved (becoming a naturalized citizen sometime after July 1828 and dropping his European titles).

[5] En route to America, he was shipwrecked in Spain and captured by the Spanish, compelling him to remain there for many months until his brother secured assistance from the American President James Monroe for his release.

[9] He created the Civil Society for the construction of French Masonry (1853-1854) and purchased the building at 16, rue Cadet, which became the Hôtel du Grand Orient de France.

[5] During the Franco-Prussian War, after the French defeat at the Siege of Metz in 1870, Murat was imprisoned with Marshal of France François Achille Bazaine.

Caroline, a Protestant, former governess at the residence of Joseph Bonaparte in Bordentown, New Jersey, was born in Charleston, South Carolina, daughter of Thomas Fraser, a Scottish emigrant to the United States and major in the Loyalist militia during the American Revolution, and his wife Ann Loughton (née Smith) Fraser.

[19] After Prince Murat's death in 1933, his widow married French writer and diplomat Count Charles de Chambrun.

[20] The remaining grandchildren were Prince Louis Napoléon Achille Charles (1878–1943), major general in the Russian Army, and Princess Antoinette Katherine (1879–1954), who married Gabrielle Johan Carlo Giuseppe Luigi Maria Nino Bortolotto Bebe.

[15] The younger was Prince Michel Anne Charles Joachim Napoléon Murat (1887–1941), who married Helena MacDonald Stallo, heiress to the Standard Oil fortune, in 1913.
