The Kennedy family (Irish: Ó Cinnéide) is an American political family that has long been prominent in American politics, public service, entertainment, and business. In 1884, 35 years after the family's arrival from County Wexford, Ireland, Patrick Joseph "P. J." Kennedy became the first Kennedy elected to public office, serving in the Massachusetts state legislature until 1895. At least one Kennedy family member was serving in federal elective office in every year from 1947, when P. J. Kennedy's grandson John F. Kennedy became a member of Congress from Massachusetts, until 2011, when Patrick J. Kennedy II (John's nephew) retired as a member of the U.S. House of Representatives from Rhode Island.
P. J.'s son Joseph P. Kennedy Sr. and his wife, Rose Fitzgerald Kennedy, had nine children, including John F. Kennedy, who served in both houses of the United States Congress and as U.S. President; Robert F. Kennedy, who served as U.S. Attorney General and as a U.S. Senator; Ted Kennedy, who served more than 46 years in the U.S. Senate; and Jean Kennedy Smith, who served as U.S. ambassador to Ireland.
