Found it interesting that Sen. John Kennedy (LA) isn't really a Kennedy.

[Beautiful Disaster]

25. Actually, if you trace Kennedy's family, it eventually leads back to Scotland.

Thomas Kennedy was born in 1618 in Dunure, Ayrshire, Scotland. He was the son of Gilbert Kennedy and Isabel Campbell. Both were born in Dunure, Ayrshire, Scotland.

Thomas Kennedy Sr. was the father of Thomas Kennedy Jr., who was born about 1648 and may have been the first Kennedy born in Ireland (though, his location of birth is listed as unknown at a few places).

Thomas Kennedy Jr. was the father of Thomas Kennedy III, who was born in 1690 - possibly Ireland.

Thomas Kennedy III was the father of John Kennedy Sr., who was born 1715 in Ireland.

John Kennedy Sr. was the father of John Kennedy Jr., who was born in 1740 in Ireland.

John Kennedy Jr. was the father of Patrick Kennedy Sr., who was born in 1760 in Ireland.

Patrick Kennedy Sr. was the father of Patrick Kennedy Jr., who was born in County Wexford around 1785.

Patrick Kennedy Jr. was the father of Patrick Joseph Kennedy, who was born in Boston in 1858.

Patrick Joseph Kennedy was the father of Joseph Patrick Kennedy, who was born in 1888 in Boston.

Of course, Joseph Patrick Kennedy is the father of John Kennedy.

This is all assuming that the ancestry is accurate, of course lol

But it sounds pretty accurate as you can read the history here:
