Catherine Daingerfield Willis Gray Murat (August 17, 1803 – August 6, 1867) was an American socialite. Her second husband was Prince Achille Murat, an exiled Napoleonic prince living in America, from 1826 to 1847. She was born near Fredericksburg, Virginia and died in Tallahassee, Florida, United States.
Catherine Daingerfield Willis was the great-grandniece of George Washington. She was a daughter of Colonel Byrd C. Willis (August 29, 1781 - 1846) and his wife Mary Lewis, the granddaughter of Fielding Lewis, George Washington's brother-in-law. Through the Lewis family, she was also a relative of explorer Meriwether Lewis.
Her parents made their first home in Orange near the Court House. Later they came to Willis Hill. Col. Willis paid little attention to the management of the plantation and instead spent his time fox hunting, racing, and attending parties. Income was derived from the race profits and the sale of fire wood.
Murat married Atchison Gray, son of John Gray of Traveller's Rest (Kearneysville, West Virginia). Atchison died less than 12 months after their marriage and their child, born after his death, died also.
About 1825, Murat came to Tallahassee with her parents, three brothers and two sisters. In 1826, she met and married her second husband, Prince Achille Murat. He was a son of Joachim Murat, former King of Naples and Caroline Bonaparte. His maternal uncles included Joseph Bonaparte, Napoleon I of France, Lucien Bonaparte, Louis Bonaparte and Jérôme Bonaparte. His maternal aunts included Elisa Bonaparte and Pauline Bonaparte.
In 1847, she inherited the 2,000-acre (8.1 km2) Lipona Plantation in Jefferson County, Florida upon the death of her husband. In 1854 she bought Bellevue, in Leon County, which became her primary residence.
Murat became involved in the nation's first successful preservation effort, the work to preserve George Washington's home. In 1858, Murat was appointed the first Vice Regent for Florida for the Mount Vernon Ladies' Association, the title given the central person in each state organizing the association's work. Working closely with Ellen Call Long, she led the efforts as the state raised $3,791 toward the restoration of Mount Vernon, the largest per capita amount raised by any of the 30 contributing states. Murat served in that post until her death. Despite her staunch Unionism, she was named master of ceremonies during the celebrations of the Florida Secession Convention in 1861. Later, during the American Civil War, Murat participated in the local "Soldiers Aid Societies," who met as sewing circles to clothe the southern troops.
Early in 1866, Napoleon III of France, a maternal first cousin of her husband, granted Murat an annuity from the French government in consideration of her losses during the Civil War. Catherine Murat died August 6, 1867 at Bellevue.
Murat's marker in the old Tallahassee Episcopal Cemetery reads:
