Nan Britton lost her libel suit over Warren Harding's daughter in 1931, and DNA proved the daughter was his in 2015

Nan Britton was born in Harding's hometown of Marion, Ohio, in 1896. Her daughter, Elizabeth Ann, was born on 22 October 1919 in Asbury Park, New Jersey, and was raised by Britton's aunt and uncle in Athens, Ohio. Britton said Harding paid $500 a month in support and that after he died in office in August 1923 his widow refused to continue. Harding left an estate of $850,000. In 1927 Britton published The President's Daughter through a company she named after the child. Police seized the printing plates at the request of the New York Society for the Suppression of Vice. The book became a bestseller. In 1928 Charles Klunk funded a rebuttal book that attacked her claims. She sued Klunk for libel. In Britton v. Klunk, tried in Toledo in 1931, she produced no proof of the affair and lost. Elizabeth Ann married Henry Blaesing in 1938. Britton died in 1991 and Elizabeth Ann on 17 November 2005. In 2015 Harding's grandnephew Peter Harding and Elizabeth Ann's son James Blaesing took AncestryDNA tests. They matched as second cousins. The result was reported on 12 August 2015. Elizabeth Ann is Harding's only known child. She never received any part of his estate^†.
