Fact check: No, Queen Elizabeth II, President Joe Biden and Pope Francis are not related

The claim: Queen Elizabeth II, President Joe Biden and Pope Francis are related to each other

Queen Elizabeth II's funeral brought many world leaders together, including President Joe Biden, who was there alongside first lady Jill Biden. Pope Francis, who first met the queen eight years ago, did not attend but chose instead to send a representative in his place.

An Oct. 14 Instagram post, though, claims Biden, Elizabeth and Francis are connected in a more significant way than each of them being a well-known public figure.

“These entities are all related family,” reads the post, which accumulated more than 3,400 likes in 10 days. “Pope Francis is Queen Elizabeths brother & Joe Biden they cousin (sic)."

Many commenters appeared to believe the claim, including a social media user who said, "All of those Criminals are related ... it's already a Fact!"

Another social media user tied the claim in the post to a baseless conspiracy theory that Biden died "a few years ago."

But the claim is false. There is no evidence the three leaders are related to one another.

In the video attached to the post, a male's voice says, "I don't have any facts behind this except for my intuition," and later references a decades-old conspiracy theory that the world is secretly run by reptilian elites who mask themselves as humans.

USA TODAY reached out to the social media user who shared the post for comment. The user did not provide additional evidence to support the claim.

Claim based on debunked 'reptilian' conspiracy theory

In 1998, former BBC sports reporter David Icke published "The Biggest Secret," which featured interviews with "two Brits who claimed members of the royal family are nothing more than reptiles with crowns," according to Time.

Since then, many prominent figures have become targets of the oft-debunked conspiracy theory, including Elizabeth and Biden, as well as Jeff Bezos and Mark Zuckerberg (who was asked directly about the claim – and denied it).

But reptilian conspiracies aside, there is no evidence that Biden, Elizabeth and Francis are related. No reputable publication or agency has ever made or proven such a claim.

A family tree of the British royal family compiled by the BBC doesn't mention Biden or Francis. Elizabeth had only one sibling, Princess Margaret, her younger sister, who died in 2002.

Pope Francis, who was born Jorge Mario Bergoglio, is originally from Argentina and is the son of Italian immigrants, according to a Vatican biography.

“His father Mario was an accountant employed by the railways and his mother Regina Sivori was a committed wife dedicated to raising their five children,” the biography says.

An in-depth article published in the New Yorker earlier this year details Biden's family history. It doesn't mention Elizabeth or Francis, but it does reference Biden's “emphasis on his Irish roots and his middle-class background.”

Two of Biden's great-great-grandfathers were originally from Ireland, according to The Irish Times.

Lead Stories has also debunked the claim.
