Note: This is just one of 1,130 family groupings listed on The Political Graveyard web site. These families each have three or more politician members, all linked together by blood, marriage or adoption.

These groupings — even the names of the groupings, and the areas of main activity — are the result of a computer algorithm working with the data I have, not the choices of any historian or genealogist.
