The Political Graveyard: A Database of American History
Incomplete List of Political Families

Listed below are 1,130 family groupings Most of these are assembled from all of the links between related politicians. Any two people who are linked are in the same family group. If A is related to B, who is related to C, who is related to D, then all four are in the same group.

(Note that links between cousins are included only if they imply at least 1/1024 common ancestry. In other words, first cousins up to seven times removed, second cousins up to five times removed, third cousins up to three times removed, and fourth cousins up to once removed. Fifth and more distant cousins are not linked.)

Family groupings are listed here if they have at least three politician members, linked by blood, marriage, or adoption. They're listed in descending order by the number of politician members; among those with the same number, the oldest families are listed first.

The largest family grouping, which I call the Three Thousand Related Politicians, is further broken down into subsets of more closely related people. An individual may appear in more than one subset.

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.

If you know of other relation between any two political figures in my database, please consider bringing it to my attention!
