The genealogy website Geni.com tells entertainment show “Extra” that the GOP and Democratic White House candidates are 19th cousins.

The first Duke and Duchess of Lancaster are Trump and Clinton’s 18th great-grandparents, according to the site's analysis.

“John of Gaunt, 1st Duke of Lancaster, married Katherine Swynford, Duchess of Lancaster, and John and Katherine are Donald and Hillary’s shared 18th great grandparents,” reports “Extra.”

Author A.J. Jacobs, who studied the Geni.com research, told the television program of the two 2016 hopefuls, “Their 19th great grandfather is King Edward III so there is precedent for ruling a country; it’s in their genes.”

The relative revelation isn’t the first time political opposites have turned out to be family members.

Former Vice President Dick Cheney’s wife, Lynne, revealed in 2007 that while researching her ancestry for her memoir, she discovered her husband and then-Sen. Barack Obama (D-Ill.) were actually eighth cousins.

“Every family has a black sheep,” an Obama spokesman said at the time.

One theory claims that every American president except for Obama all share a common European royal ancestor.
