The U.S. has seen father-son pairs in the White House, and even one grandfather-grandson duo, but as of 2020, Franklin D. Roosevelt has the most presidential relatives in his family tree.

According to both History.com and the Franklin D. Roosevelt Presidential Library and Museum, genealogists have determined that FDR was distantly related to at least 11 previous U.S. presidents; 5 by blood and 6 by marriage.

Most Americans are probably aware that Franklin Delano Roosevelt (the 32nd U.S. president) was a fifth cousin of Theodore Roosevelt (26th president). In addition, FDR was related to ten other former presidents. On the Roosevelt side, there were just two; Teddy and Martin Van Buren. On the Delano side, he was related to nine more; John Adams, James Madison, John Quincey Adams, William Henry Harrison, Zachary Taylor, Andrew Johnson, Ulysses S. Grant, Benjamin Harrison, and William Howard Taft. (In addition he was also related to George Washington by marriage.)

Roosevelt’s family tree extended even further than the White House. His roots can be traced to several other historical figures, including British Prime Minister Winston Churchill, Douglas MacArthur, and two famous Confederate leaders; Jefferson Davis and Robert E. Lee.
