Which U.S. presidents can trace ancestry to Mayflower passengers and which specific pilgrims are they descended from?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
A notable handful of U.S. presidents have verifiable lines to one or more Mayflower passengers; those most consistently documented in the genealogical literature include John Adams and John Quincy Adams, Franklin D. Roosevelt, George H. W. Bush and George W. Bush, Ulysses S. Grant, Zachary Taylor, and James A. Garfield, each tied to specific Mayflower men and women named in family‑history sources [1] [2] [3] [4] [5]. Genealogical claims vary in depth and certainty — some presidents descend from multiple Pilgrims through many generations, while other alleged links are weaker or involve later Plymouth settlers who did not sail on the Mayflower [6] [7].
1. Presidential descendants tied to specific Mayflower passengers
The Adamses (John Adams and his son John Quincy Adams) trace lines back to John Alden and Priscilla Mullins — Alden served as a Mayflower crewman and Priscilla came with her parents as passengers — a connection cited repeatedly in popular genealogies and historical summaries [1] [8]. Franklin D. Roosevelt’s Mayflower roots include descent from Isaac Allerton, Francis Cooke and John Howland, making Roosevelt a descendant of several prominent early Plymouth families as reported by family‑history organizations and New England genealogical research [4] [9]. The Bush political dynasty — George H. W. Bush and George W. Bush — have established lines to John Howland and other Pilgrims such as Francis Cooke and John Tilley according to Mayflower and educational heritage sources [3] [4] [10]. Ulysses S. Grant is listed among presidents with Mayflower ancestry in family‑history roundups and genealogical compilations, though summaries do not always enumerate every Pilgrim ancestor in a single short piece [2] [5]. Zachary Taylor is reported to descend from Mayflower leaders William Brewster and Isaac Allerton in ancestry overviews that connect 19th‑century presidents back to early colony founders [5] [8]. James A. Garfield has been linked to John Billington, a contentious Mayflower passenger, in lists of famous Mayflower descendants [1].
2. Multiple lines, overlapping pedigrees, and why so many presidents appear
Genealogists and Mayflower societies note that a relatively small early colonial population combined with centuries of family expansion makes Mayflower ancestry common among Americans of colonial descent; some Pilgrims like John Howland are ancestors to millions and therefore to multiple presidents [3]. That explains overlapping pedigrees: the same Pilgrim surname can recur across presidential family trees [3] [10]. Published lists compiled by FamilySearch, the General Society of Mayflower Descendants and Mayflower heritage sites aggregate decades of specialized research to identify which presidents descend from which passengers, but they also reflect the tendency of prominence and survivorship to increase the visibility of certain lineages [2] [11] [9].
3. Limits, disputes and common misunderstandings in presidential Mayflower claims
Not every claim is equally documented in short web summaries: some sources name presidents as “Mayflower descendants” without listing the exact pilgrim or citing primary proof, and prominent modern presidents such as Joe Biden and Donald Trump have no widely accepted Mayflower descent according to the Mayflower Society’s reporting [12]. Barack Obama’s connection to Plymouth appears in some coverage through later Plymouth settlers like Thomas Blossom who came on a different ship (the Speedwell), illustrating a common confusion between “Plymouth colony settler” and “Mayflower passenger” — Blossom was not a Mayflower passenger, and sources stress that distinction [6]. Genealogical certainty requires tracing documented lineages and consulting primary records; many popular lists condense that complexity for readers [7].
4. What this lineage picture tells about American heritage and political narrative
The concentration of Mayflower ancestry among several presidents is as much a reflection of demographic history as it is of symbolic inheritance: researchers and heritage organizations emphasize the historic interest of these connections while also acknowledging that Mayflower descent is widespread among Americans of colonial New England stock and does not by itself confer any singular cultural or political meaning [3] [9]. Sources compiled by Mayflower societies, FamilySearch and historical outlets provide the best public inventories of which presidents descend from which Pilgrims, but careful scholars caution against treating short lists as exhaustive without consulting the underlying genealogical studies [2] [7].
