COLUMBUS — The grandson of U.S. President Warren G. Harding and his lover, Nan Britton, went to court to get the Republican’s remains exhumed from the presidential memorial where they have lain since 1927.

James Blaesing told an Ohio court that he is seeking Harding’s disinterment as a way “to establish with scientific certainty” that he is the 29th president’s blood relation.

The dispute looms as benefactors prepare to mark the centennial of Harding’s 1920 election with site upgrades and a new presidential center in Marion, the Ohio city near which he was born in 1865. Blaesing says he deserves to “have his story, his mother’s story and his grandmother’s story included within the hallowed halls and museums in this town.”

A branch of the Harding family has pushed back against the suit filed in May — not because they dispute Blaesing’s ancestry, but because they don’t.

They argue they already have accepted as fact DNA evidence that Blaesing’s mother, Elizabeth Ann Blaesing, was the daughter of Harding and Britton and that she is set to be acknowledged in the museum. Harding had no other children.

“Sadly, widespread, public recognition and acceptance by the descendants, historians, and biographers (and Mr. Blaesing himself) that Mr. Blaesing is President Harding’s grandson is not enough for him,” relatives said in a court filing. They called the lawsuit a ploy for attention.
