It is estimated that 17 million people worldwide, including the British Royal Family, Iranian Royalty, and the family of Dracula, are direct descendents of Genghis Khan.

A London restaurant chain is offering customers free DNA testing to see if they’re descended from Genghis Khan.

Restaurant Shish has promised free meals for any found to be related to the notorious Mongol leader.

The unusual promotion is to mark the Mongolian government’s decision to allow citizens to have surnames for the first time since they were banned by the communists in the 1920s.

Some 50,000 Mongolians now proudly claim direct descent from and bear the name of Genghis Khan.

Shish has teamed up with DNA-based research company Oxford Ancestors to offer descendants food from their ancestral homelands.

From Saturday July 3 to Friday July 9, diners at the Shish restaurant venues in London’s Hoxton and Willesden Green will have the opportunity to have their DNA sent off for analysis

The procedure needs only a small brush to be rubbed quickly around the inside cheek of the participant. The sample is then sent off for analysis which takes around two months.

It is estimated that 17 million people worldwide, including the British Royal Family, Iranian Royalty, and the family of Dracula, are direct descendents of Genghis Khan.

The conqueror founded an empire which, at its height, stretched from The Sea Of Japan, across Russia and northern India, to the edges of modern day Eastern Europe.
