Rose Elizabeth Fitzgerald Kennedy (July 22, 1890 – January 22, 1995) was an American philanthropist, socialite, and a member of the Kennedy family. She was deeply embedded in the "lace curtain" Irish Catholic community in Boston, where her father John F. Fitzgerald was mayor. Kennedy was the wife of businessman and investor Joseph P. Kennedy Sr., who was United States Ambassador to the United Kingdom, formally known as Ambassador to the Court of St. James's in the UK. Their nine children included President John F. Kennedy, Senator Robert F. Kennedy, and longtime Senator Ted Kennedy. In 1951 she was ennobled by Pope Pius XII, becoming the sixth American woman to be granted the rank of Papal countess.
