The family backgrounds of recent U.S. presidents tell a long history of immigration and interwoven European ancestry, with English, Irish, Scottish and German heritage appearing most frequently across the White House since the 20th century.
President Donald Trump, who returned to office in January 2025, traces his ancestry primarily to Germany through his paternal grandparents, Friedrich Trump and Elisabeth Christ, who emigrated from the Kingdom of Bavaria in the 1880s. On his mother's side, he descends from Scottish immigrants from the Isle of Lewis in the Outer Hebrides.
Joe Biden's documented ancestry is predominantly Irish and English, with additional French roots. Much of his paternal family originated in Counties Louth and Mayo in Ireland before emigrating to Pennsylvania during the 19th century.
Barack Obama has one of the most internationally diverse family backgrounds of any U.S. president. His father, Barack Obama Sr., was a Luo from Kenya, while his mother's ancestry includes English, Irish, Scottish, German, French, Swiss and Welsh forebears, as documented by professional genealogists and academic studies.

English ancestry remains the most common thread among modern U.S. presidents.
Bill Clinton, Ronald Reagan, Lyndon B. Johnson, Richard Nixon, Harry Truman, Gerald Ford, George H. W. Bush, George W. Bush and Franklin D. Roosevelt all trace substantial portions of their ancestry to early English settlers who arrived during the colonial period.
Irish ancestry is also widespread. John F. Kennedy became the first Irish Catholic president in 1961, while Biden, Clinton and Reagan all have well-documented Irish roots.
Scottish ancestry appears repeatedly as well, reflecting migration from both Scotland and the Ulster Scots community that settled extensively across colonial America during the 18th century.
German heritage is another recurring feature, particularly among Dwight D. Eisenhower, whose family descended from German immigrants who arrived in Pennsylvania in the 18th century. Eisenhower also had Swiss ancestry through his maternal line.
Immigration shaped America's political leadership
Several presidents reflect America's broader immigration story.
Gerald Ford had English, Scottish and Polish ancestry. Richard Nixon combined English, German, Welsh and Ulster Scots heritage. George W. Bush and George H. W. Bush both descended from families with English, German, Dutch, Irish, French, Scottish and Swedish roots.
Franklin D. Roosevelt's ancestry included Dutch settlers whose family arrived in New Netherland during the 17th century, alongside English, French and Scottish lines.
