Politico.com’s report on Rep. Patrick Kennedy’s plan to retire from Congress notes this:

Kennedy, 42, was first elected to the House in 1994. His departure will leave Congress without a Kennedy for the first time since 1962, when his father was elected to the Senate seat held previously by his uncle, John F. Kennedy.

In a two-minute video retirement announcement, Kennedy invokes the memory of his father as he explains his decision to leave the House.
