Republican presidential front-runner Donald Trump and his Democratic counterpart Hillary Clinton are far from being friends and in fact have even hurled nasty names against one another.

Trump has called the former first lady "Crooked Hillary," while she has labelled the business magnate the "donkey of the decade."

In one of her recent speeches, Clinton said Trump scares her because he says the wrong things for America. "I mean, he's setting people against each other, he's inciting violence, and what he's doing, you know, to basically in so many ways play to the worst instincts of people is just in violation of American values and New York values for sure," she said.

Now comes the report that the two presidential hopefuls are actually distantly related. The two are "19th cousins, descending from 14th-century 1st Duke of Lancaster John of Gaunt and his third wife Katherine Swynford," United With Israel reports.

Swynford was originally Gaunt's mistress, but they later got married after Swynford divorced his wife, according to the report. Gaunt was a royal of the 14th century since he was the son of King Edward III, it adds.

Gaunt and Swyndord's children include Trump's 17th great-grandfather John Beaufort and Clinton's 17th great-grandmother Joan Beaufort, according to MyHeritage.

"Clinton claims the lineage to her 18th great-grandparents through the Rodham family of her father's side, while Trump is related to her through his mother Mary Anne Macleod, who was born in Scotland. The common relative means that the Democrat and Republican are 19th cousins," the Daily Mail reports.

The two also have a lot of other well-known distant relatives. Clinton and "Mr. and Mrs. Smith" actress Angelina Jolie are ninth cousins twice removed, while Trump's known ancestors include grandfather Friedrich Drumpf, a German immigrant in the late 1800s who owned a restaurant in Seattle and later got involved in the Yukon gold rush.
