A whistle-stop tour of every US president's ancestry
10+ minute read
By Niall Cullen
From George Washington to Joe Biden, here's a quick overview of the (sometimes surprising) genealogy of every US president in history.
The family history of powerful political figures is always interesting to delve into and they don't come more powerful than the President of the United States.
Some American presidents' family trees are widely documented. Others, you may be less familiar with. What's more, some of them may have family connections you don't expect.
Ancestry of early US presidents
Here, we've provided quickfire summaries of the first six US presidents' family lines.
George Washington's great-grandfather was from Hertfordshire, England. He settled in the Colony of Virginia in 1657 after coming ashore from a shipwreck. In fact, almost all of the first president's direct ancestors can be traced back to England.
John Adams' roots also lie in England. His great-grandfather emigrated to Massachusetts from Essex in the mid-1600s.
The first president with no First Lady, Thomas Jefferson's wife Martha died before he assumed office. It's thought that he was of English and Welsh descent. In later life, he wrote; "The tradition in my father's family was that their ancestor came to this country from Wales, and from near the mountain of Snowden, the highest in Great Britain.” The Welsh connection has yet to be proved. Perhaps it was just a family story?
James Madison's great-grandfather, Captain Isaac Madison, migrated to Virginia from London. The Madison family put down roots in Virginia and generations of powerful landowners would culminate with James becoming the fourth president of the United States.
James Monroe was the first US President with definite family connections to Scotland. His great-great-grandfather, Patrick Andrew Monroe left Scotland for America in the 1600s and brought with him ancient ties to the Scottish Clan Munro. On his mother's side, James Monroe also has Welsh origins.
John Quincy Adams
The sixth President of the United States was the son of the second, John Adams, and shared his English heritage.
Ancestry of presidents from the 19th century
John Quincy Adams was in office until 1829. Here's a rundown of the roots of the men who followed.
Andrew Jackson was the first president with genealogical ties to Ireland. His parents emigrated from Northern Ireland in 1765, a couple of years before he was born. His father's family also connects him back to Yorkshire.
Martin Van Buren
As his surname may suggest, Martin Van Buren was the first US President with no direct British or Irish connections. Both of his parents were of Dutch descent. His father served in the American Revolution.
William Henry Harrison
William Henry Harrison was the last US President born as a British subject and the first who died in office, just 31 days into his term. His family came to Virginia from England in the 1630s.
Like his presidential running mate William Henry Harrison, Tyler was descended from English aristocracy. His father, John Tyler Sr. was a close friend and one-time roommate of Thomas Jefferson.
James K Polk
The Polk family were Presbyterian farmers of Scotch-Irish descent. They came to America in the late 1600s, first to Maryland, then Pennsylvania, and finally settling in North Carolina.
Zachary Taylor was another American president with English roots. He is descended from Mayflower leaders William Brewster and Isaac Allerton. Through the same family line, Zachary Taylor is also the second cousin of President James Madison.
According to Gary Boyd Roberts, author of Ancestors of American Presidents, Milliard Fillmore is one of five US presidents you’re most likely to be related to. The others are Richard Nixon, Franklin Roosevelt, Rutherford Hayes, and William Howard Taft. Fillmore's original immigrant ancestor was John Fillmore, a mariner who settled in Massachusetts.
Franklin Pierce was a sixth-generation descendant of Thomas Pierce, who emigrated from Norwich, England in the mid-1600s. His father fought in the American Revolutionary War, while two of his older brothers served in the War of 1812.
Both of James Buchanan's parents were descended from Ulster Scots. His father, James Senior, was a farmer and merchant who came to America from Donegal, Ireland in 1783. He was the only US president to never marry, so no First Lady served during his time in office.
Arguably one of America's most famous presidents, Abraham Lincoln was of English descent. His ancestor, Samuel Lincoln, emigrated from Norfolk to Massachusetts in 1638. From there, the family moved west through New Jersey, Pennsylvania, Virginia, and Kentucky, where Abraham Lincoln was born in 1809.
Andrew Johnson's genealogy is a mix of English, Scots-Irish, and Irish descent. His mother's maiden name, McDonough, reflects his Celtic roots. Johnson was the first US president to be impeached.
Ulysses S. Grant
Born Hiram Ulysses Grant, the 18th president of the United States had English and Ulster-Scots ancestors. He also had French bloodlines from his paternal grandmother. Grant also has family connections to the Mayflower settlers and a distant link to President Franklin D. Roosevelt.
Rutherford B. Hayes
Descended from a family of colonists, Hayes' earliest immigrant ancestor came from Scotland in 1625. He had several well-known close relatives including Congressman John Noyes, sculptor Larkin Goldsmith Mead, and radical preacher John Humphrey Noyes.
James A. Garfield
James Garfield's ancestor, Edward Garfield, settled in Massachusetts after leaving Warwickshire, England around 1630. James' father, Abram was born in New York, while his mother, Eliza came from New Hampshire. On his mother's side, James' forefathers are said to have included a Welsh knight.
Chester A. Arthur
Chester Arthur's family roots include English, Welsh, and Northern Irish ancestors. His father was born into a Presbyterian family in County Antrim and emigrated to Canada in the early 1800s. During his presidential campaign, opponents claimed that Arthur wasn't born in the United States and was therefore ineligible to take office. Obviously, the accusations didn't stick.
Ironically, Grover Cleveland's earliest immigrant ancestor came from Cleveland, England in 1635. As well as English roots, he has Anglo-Irish and German Quaker ancestors. Cleveland is distantly related to General Moses Cleaveland, whom the city of Cleveland, Ohio is named after. Grover was actually his middle name - he was born Stephen and adopted his middle name in adulthood.
Benjamin Harrison has the unique accolade of being the only grandson of another American president. His grandfather, William Henry Harrison, was the ninth president. His great-grandfather Benjamin Harrison V, was a founding father who signed the Declaration of Independence.
Ancestry of presidents from the 20th century
William McKinley led America into the 20th century when he took office in 1897. Here, you'll find a summary of his family heritage, along with the 17 men who followed him during the 1900s.
The McKinley family were of English and Scots-Irish descent. William's earliest immigrant ancestor, David McKinley came to Pennsylvania from County Antrim in the 1700s. William's mother's family, the Allisons, were among the earliest settlers in Pennsylvania. McKinley was the last serving president who fought in the American Civil War.
It seems Theodore Roosevelt was the first US president with an abundant mix of European heritage. Research has revealed Dutch, Scots-Irish, English, German, Welsh, French, and Scottish lineage, including a rather intriguing connection to Robert the Bruce. Theodore is distantly related to the second of the Roosevelt presidents, Franklin D. They were fifth cousins.
William Howard Taft
Richard Robert Taft, the first known ancestor in William's famous family, died in County Louth, Ireland in 1700. His son, Robert Senior, emigrated to Massachusetts and married an Englishwoman, Sarah Simpson. One branch of the Taft family includes Lydia Taft, America's first female voter. She was William's great-great-great grand-aunt.
Born Thomas Woodrow Wilson, the 28th president's family had Scots-Irish roots. His paternal grandparents immigrated to Ohio from County Tyrone in 1807. While on his mother's side, Woodrow Wilson's grandfather hailed from Paisley, Scotland.
Warren G. Harding
As well as English, Welsh, and Scottish ancestors, Warren G. Harding’s heritage includes Dutch connections. His mother descended from the well-known Van Kirk family.
Calvin Coolidge is the only US president who was born on Independence Day. The Coolidge family were among the earliest settlers in New England. Calvin's ancestor, John Coolidge put down roots in Massachusetts after he emigrated from Cambridgeshire, England around 1630. Coolidge has deep-rooted connections to the American Revolutionary War and King Philip's War.
Herbert Hoover has German, Swiss, and English ancestors. His parents' families were Quakers and were among the earliest settlers in the West Branch, Iowa region, where Herbert was born. Hoover's mother came from Canada originally.
Franklin D. Roosevelt
Franklin Delano Roosevelt was born into a well-known Dutch-American family in New York. As we mentioned earlier, he was distantly related to the 26th president, Theodore Roosevelt. FDR's family ties were very intertwined. His parents were sixth cousins while his wife, Eleanor, was his fifth cousin once removed.
Harry S. Truman
The ‘S’ in Truman’s name is a nod to his grandfathers, Anderson Shipp Truman and Solomon Young. The Truman family story can be predominantly traced back to England with some Scotch-Irish, German, and French roots also thought to be present.
Dwight D. Eisenhower
The Eisenhauer family first immigrated to a Pennsylvania Dutch community from Karlsbrunn, Germany in the 1740s. The distinctly German-sounding surname is German for iron miner and was anglicized as the generations progressed. Dwight's family moved to Kansas in the 1880s and later to Texas, where he was born in 1890.
John F. Kennedy
JFK has well-documented Irish roots. All of his great-grandparents were Irish immigrants who made new lives in Massachusetts and he was America's first Irish-Catholic president. The Fitzgerald and Kennedy families can be traced to counties Limerick, Cavan, Cork, and Wexford, where his ancestral homestead can be visited today.
Lyndon B. Johnson
Lyndon Baines Johnson has English, German, and Ulster Scots origins. His maternal great-grandfather, George Washington Baines was a renowned Baptist minister in Texas, Arkansas, and Louisiana and served as the president of Baylor University during the American Civil War. Johnson City, Texas is named after James Polk Johnson, Lyndon’s second cousin.
Nixon has distant family connections to Jimmy Carter, Amelia Earhart, and Bill Gates (among others) through a common ancestor - Thomas Cornell, one of New England's earliest settlers. Like his brothers, Richard was named after famous British kings. In his case, Richard the Lionheart.
Born Leslie Lynch King Jr, Gerald Ford has English heritage on both parents’ sides of the family, as well as some maternal Scottish connections. His grandmother, Adele Augusta Ayer Gardner was a member of the Daughters of the American Revolution. Ford was renamed after his stepfather when his mother remarried.
James Earl Carter Jr. descends from English immigrant Thomas Carter, who settled in Virginia in 1635. Generations of Carters before Jimmy worked as cotton farmers in Georgia, where he was born. Carter was the first US president born in a hospital.
Ronald Reagan's paternal great-grandparents emigrated from County Tipperary, Ireland, while his maternal bloodlines included English, Irish, and Scottish relatives. Reagan's presidential credentials don't just relate to leading the United States. He was elected president of the Screen Actors Guild twice during his acting career.
George H. W. Bush
The first American-born member of the Bush family was Samuel Bush in 1647. Before then, their roots stretched back to England and Germany. Dubbed "the most successful political dynasty in American history", as well as a father and son duo of US presidents, over the years the family has included senators, state governors, and famous entertainment and sports stars. Supposedly, the Bushes also have links to the British Royal Family.
Born William Jefferson Blythe III, Bill Clinton has English and Scotch-Irish family lines. His forefathers first came to America at the time of the Thirteen Colonies. Clinton's scandalous backstory includes a bigamous father, an abusive stepfather, and his impeachment for his affair with White House intern, Monica Lewinsky. As a young boy, Bill Clinton met and was inspired by President John F. Kennedy.
