Believe it or not, British Prime Minister David Cameron's great-great-grandfather, a British cavalryman, helped to suppress the Sepoy mutiny of 1857.
William Low is said to have left behind graphic accounts of how he slew rebels with his sabre and participated in a mass hanging of civilians during the two-year mutiny against British rule more than 150 years ago, The Telegraph reports.
Low also reveals how he came close to losing a hand, was cut to the bone and almost lost an ear in combat during the uprising.
Cameron has gone on record to say that his ancestors were involved in 'empire building' in India.
Had the full story of his great-great-grandfather's involvement in suppressing the mutiny become public before his recent trip to India, it could have caused considerable diplomatic embarrassment.
Genealogist Nick Barratt, who worked on the BBC programme Who Do You Think You Are, traced the prime minister's family tree.
William Low was the grandfather of Sir William Mount, who married Elizabeth Llewellyn in 1929. The couple became Cameron's maternal grandparents.
Officials at 10, Downing Street declined to comment on Cameron's ancestry.
