How Many US Presidents Were Sons of Presidents?

Across more than two centuries of American elections, the presidency has rarely passed from father to son. Only two of the 45 people who have served as US president through 2026 were sons of former presidents (1 in 22.5): John Quincy Adams and George W. Bush. Counting all 47 presidencies from George Washington in 1789 through Donald J. Trump’s second inauguration in January 2025, 45 distinct individuals have held the office because Grover Cleveland (22nd and 24th) and Donald J. Trump (45th and 47th) each served two nonconsecutive terms. When 23rd president Benjamin Harrison (1889 to 1893), the grandson of ninth president William Henry Harrison (1841), is added, three of the 45 individuals who have served as president (6.67%, or 1 in 15.0, our arithmetic) were the son or grandson of an earlier president.

John Quincy Adams (1767 to 1848) was the first presidential son to reach the White House, taking office as sixth president on March 4, 1825, exactly 24 years after his father, second president John Adams (1797 to 1801), left office. Beyond that family link, Adams’s career stands alone in US political history: he served as a foreign minister under four presidents, negotiated the Treaty of Ghent ending the War of 1812, shaped the Monroe Doctrine as eighth Secretary of State, won the only House contingent presidential election conducted under the 12th Amendment, and then served nine consecutive terms in the US House of Representatives (1831 to 1848), the only former president ever elected to the House.

Born on July 11, 1767, in Braintree (now Quincy), Massachusetts, John Quincy Adams was the son of John Adams and Abigail Smith Adams, born two days before the death of his mother’s grandfather, Colonel John Quincy, for whom he was named. Over the next eight decades, his life spanned the American Revolution, the founding of the constitutional republic, the expansion of the United States to the Pacific Ocean, and the growing sectional crisis over slavery that preceded the Civil War.

How rare are father-and-son and grandfather-and-grandson presidents?

Through 2026, the United States has had 47 numbered presidencies held by 45 individuals. Only two father-and-son pairs and one grandfather-and-grandson pair appear on that roster. John Quincy Adams waited 24 years after John Adams left office in 1801 before taking the oath in 1825, and that father-and-son precedent stood alone for 176 years until George W. Bush (43rd president, 2001 to 2009) followed his father George H. W. Bush (41st president, 1989 to 1993) after an eight-year gap.

Whether measured by individual people or by numbered administrations, direct lineal succession in the presidency is an outlier. Out of 45 individual presidents, 2 were sons of former presidents (4.44%, or 1 in 22.5, our arithmetic); out of 47 presidencies, 2 were held by sons of former presidents (4.26%, or 1 in 23.5, our arithmetic). Both John Adams and John Quincy Adams served a single four-year term and lost reelection to the same rival they had faced four years earlier: John Adams lost the 1800 election to Thomas Jefferson, and John Quincy Adams lost the 1828 election to Andrew Jackson.

From teenaged diplomat to eighth Secretary of State

Few American presidents entered office with longer diplomatic preparation than John Quincy Adams. In 1778, at age 10, he sailed to France with his father, who was serving as a US commissioner in Paris. Returning to Europe in 1779, he studied at Leiden University in the Netherlands in 1780 and began keeping the daily diary that he maintained for the next 60 years. In 1781, at age 14, he traveled to St. Petersburg as private secretary and French interpreter to Francis Dana, the American envoy to Russia, and in 1783, at age 16, he served as secretary to his father during the negotiations for the Treaty of Paris that ended the Revolutionary War.

Returning home to Massachusetts, Adams graduated from Harvard University in 1787, studied law, was admitted to the bar in 1790, and opened a law practice in Boston. President George Washington appointed him Minister Resident to the Netherlands on May 30, 1794 (serving until June 20, 1797), and praised him as “the most valuable public character we have abroad.” Under his father’s administration, Adams served as Minister Plenipotentiary to Prussia in Berlin from 1797 to 1801. Before departing for Prussia, he married Louisa Catherine Johnson on July 26, 1797, in London. Born in London on February 12, 1775, to Maryland merchant and first US consul in London Joshua Johnson and British mother Catherine Nuth, Louisa Catherine Adams became the first First Lady born outside the United States, a distinction she held alone for 192 years until Melania Trump (born April 26, 1970, in Novo Mesto, Slovenia) became the second foreign-born First Lady in January 2017.

Elected to the Massachusetts state senate in 1802 and to the US Senate as a Federalist taking office on March 4, 1803, Adams repeatedly broke with Federalist party orthodoxy by supporting President Thomas Jefferson’s Louisiana Purchase in 1803 and Embargo Act in 1807. After the Federalist-controlled Massachusetts legislature elected his successor six months early, Adams resigned his Senate seat on June 8, 1808. President James Madison returned him to diplomacy as Minister Plenipotentiary to Russia from 1809 to 1814; while in St. Petersburg in February 1811, Adams was nominated and confirmed by the Senate as an Associate Justice of the US Supreme Court, but declined the seat. He went on to lead the American delegation that signed the Treaty of Ghent on December 24, 1814, ending the War of 1812, and served as Envoy Extraordinary and Minister Plenipotentiary to the United Kingdom from 1815 to 1817, where he negotiated the Rush-Bagot Pact of 1817 limiting naval armaments on the Great Lakes.

Appointed eighth US Secretary of State by President James Monroe on March 5, 1817 (serving from September 22, 1817, to March 3, 1825), Adams oversaw a sweeping reorganization of US borders and hemispheric policy. He guided the Convention of 1818 with Great Britain, which fixed the US-Canadian boundary along the 49th parallel to the Rocky Mountains and established joint occupation of the Oregon Country; negotiated the Adams-Onis Treaty of 1819 with Spain, securing the acquisition of Florida and Spain’s claim to the Oregon Country to the Pacific; and helped craft the 1823 Monroe Doctrine, insisting that the United States issue the declaration unilaterally rather than jointly with Great Britain.

The 1824 contingent election and nine terms in the US House

The presidential election of 1824 is one of only two presidential elections in US history decided by the House of Representatives (2 of 60 presidential elections from 1788-89 through 2024, or 1 in 30.0, our arithmetic), alongside the 1800 electoral tie between Thomas Jefferson and Aaron Burr, and it remains the only contingent election held in the House since the 12th Amendment was ratified in 1804. It is also the first of five US presidential elections (5 of 60, or 1 in 12.0, our arithmetic) in which the candidate who won the national popular vote lost the presidency, followed by Samuel Tilden against Rutherford B. Hayes in 1876, Grover Cleveland against Benjamin Harrison in 1888, Al Gore against George W. Bush in 2000, and Hillary Clinton against Donald J. Trump in 2016.

In the 1824 contest across 24 states, four candidates from the splintered Democratic-Republican Party divided the 261 electoral votes without any candidate reaching the 131-vote majority: Senator Andrew Jackson of Tennessee won 99 electoral votes (37.93%, 32 short of a majority) and a plurality of the national popular vote, Secretary of State John Quincy Adams won 84 electoral votes (32.18%), Treasury Secretary William H. Crawford of Georgia won 41 (15.71%), and Speaker of the House Henry Clay of Kentucky won 37 (14.18%). Because the 12th Amendment restricted the House contingent election to the top three Electoral College finishers, fourth-place finisher Henry Clay was excluded from the ballot. Clay cast his influence behind Adams, who shared his support for internal improvements and protective tariffs, and on February 9, 1825, the House elected Adams on the first ballot with 13 of the 24 state delegations (54.17%, our arithmetic) to 7 states for Jackson (29.17%) and 4 for Crawford (16.67%). When Adams appointed Clay to succeed him as Secretary of State, Jackson accused the pair of a “corrupt bargain,” declaring that “[t]he Judas of the West has closed the contract and will receive the thirty pieces of silver.” Jackson’s supporters in Congress blocked most of Adams’s domestic program, which called for a national university, a national naval academy, federally funded canals and turnpikes, and an astronomical observatory (“light-houses of the skies”), before Jackson defeated Adams in the 1828 rematch.

After leaving the White House in March 1829, Adams returned to public office on November 1, 1830, winning election to the US House of Representatives from southeastern Massachusetts with nearly three-quarters of the vote in a three-way race. Dismissing the notion that House service demeaned an ex-president, Adams wrote in his journal before the election that “no person could be degraded by serving the people as a Representative in Congress” and added that an ex-president would not be degraded “by serving as a selectman of his town, if elected thereto by the people.” Taking his seat on March 4, 1831, in the 22nd Congress, he won reelection eight times as an Anti-Jacksonian, Anti-Mason, and Whig, serving nine consecutive terms across nearly 17 years through the 30th Congress.

In the House, Adams became the chamber’s foremost opponent of slavery’s expansion and champion of the right of petition:

• Repealing the House gag rule (1836 to 1844): When the House adopted rules automatically tabling all antislavery petitions without debate, Adams fought the restriction at every session until his motion to repeal the gag rule carried by a vote of 108 to 80 in 1844.
• Arguing the Amistad case before the US Supreme Court (1841): After 53 abducted Africans from Sierra Leone seized the Cuban schooner Amistad on July 1, 1839, and the US brig Washington seized the vessel off Long Island, New York, on August 24, 1839, taking it to New London, Connecticut, 73-year-old Representative Adams defended the Africans before the US Supreme Court in 1841 in an 8.5-hour argument grounded in international treaties prohibiting the slave trade and the Declaration of Independence; Senior Justice Joseph Story wrote and read the Court’s decision holding that the kidnapped Africans were free individuals who had never been slaves and ordering their immediate release, allowing 35 survivors to return to their homeland.
• Advancing American science: At age 77 in 1844, Adams traveled to Ohio to lay the cornerstone of the Cincinnati Observatory, and in 1846 he helped secure the congressional charter establishing the Smithsonian Institution.

On February 21, 1848, after voting in the negative during a House debate on a resolution honoring military officers in the US-Mexican War, the 80-year-old Adams suffered a stroke and collapsed at his desk on the House floor. Fellow members carried him first to the Capitol Rotunda and then to the Speaker’s Room (today the Lindy Claiborne Boggs Congressional Women’s Reading Room), where he thanked the officers of the House, lapsed into a coma, and died two days later on February 23, 1848. Four years later, when Louisa Catherine Adams died on May 15, 1852, in Washington, DC, both the Senate and the House of Representatives adjourned in mourning for a former First Lady for the first time in US history.
