Demarest-Blauvelt family of Nyack, New York

Note: This is just one of 1,325 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.

This specific family group is a subset of the much larger Four Thousand Related Politicians group. An individual may be listed with 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.

The Political Graveyard is a web site about U.S. political history and cemeteries. Founded in 1996, it is the Internet's most comprehensive free source for American political biography, listing 338,260 politicians, living and dead.
 
  The coverage of this site includes (1) the President, Vice President, members of Congress, elected state and territorial officeholders in all fifty states, the District of Columbia, and U.S. territories; and the chief elected official, typically the mayor, of qualifying municipalities; (2) candidates at election, including primaries, for any of the above; (3) all federal judges and all state appellate judges; (4) certain federal officials, including the federal cabinet, diplomatic chiefs of mission, consuls, U.S. district attorneys, collectors of customs and internal revenue, members of major federal commissions; and political appointee (pre-1969) postmasters of qualifying communities; (5) state and national political party officials, including delegates, alternate delegates, and other participants in national party nominating conventions; (6) Americans who served as "honorary" consuls for other nations before 1950. Note: municipalities or communities "qualify", for Political Graveyard purposes, if they have at least half a million person-years of history, inclusive of predecessor, successor, and merged entities.
