For decades, some have claimed that Harding had some African-American heritage, an argument that received renewed attention after President Obama’s election in 2008\. Harding himself once [told](https://books.google.com/books?id=ldvcd6G-FMAC&pg=PA165&lpg=PA165&dq=one+of+my+ancestors+may+have+jumped+the+fence+harding&source=bl&ots=s%5FuUGCnv3o&sig=eDSf%5FqtFRDHBsj7LKmhciWdLArM&hl=en&sa=X&ved=0CDkQ6AEwBmoVChMI%5FuTQ5K6zxwIVAaYeCh3ktw2H#v=onepage&q=one%20of%20my%20ancestors%20may%20have%20jumped%20the%20fence%20harding&f=false) a reporter that “one of \[his\] ancestors may have jumped the fence.” But Julie Granka, population geneticist at genealogy company Ancestry.com, which conducted the tests, [told](http://www.nytimes.com/2015/08/19/us/politics/dna-that-confirmed-one-warren-harding-rumor-refutes-another.html?smid=tw-share&%5Fr=0) the New York _Times_ that the tests did not find any “detectable genetic signatures of sub-Saharan African heritage” in any of Harding’s close relatives tested in the DNA exercise. It was “very unlikely” that Harding had a black ancestor within four generations, she said. Dr. Peter Harding, the president’s grandnephew and also part of the DNA tests, said that he was disappointed. “I was hoping for black blood,” he told the _Times_. **Read Next:**[_DNA Tests Proved This 92-Year-Old Presidential Rumor_](http://time.com/3996052/warren-harding-mistress/) ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4002116/warren-harding-african-american/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4002116/warren-harding-african-american/"},"headline":"DNA Tests Show This President Did Not Have Black Ancestors","datePublished":"2015-08-18T20:36:43.000Z","dateModified":"2026-02-22T10:15:55.448Z","description":"DNA tests that proved Warren Harding had a child by his mistress have solved another historical mystery: He did not have African-American ancestors.","url":"https://time.com/4002116/warren-harding-african-american/","keywords":["White House","History"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt3b8ab8ffacf0f216/69885f29cf40a87c33c3f342/warren-harding.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Aditya Agrawal","jobTitle":null,"url":"https://time.com/author/aditya-agrawal/"}],"articleSection":"History","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt3b8ab8ffacf0f216/69885f29cf40a87c33c3f342/warren-harding.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Warren G Harding, 29th President of the United States, (1933).
