Two Belgian researchers matched Hitler’s DNA to 39 people, including three brothers in Long Island, New York, who are directly descended from the Nazi leader.

Their family changed their name after moving to America, and the grand-nephews, Louis, Brian and Alexander Stuart-Houston, are said to have made a pact to end Hitler’s bloodline.

Along with their youngest brother Howard, who died in a car crash, they never married or had children. Louis and Brian live in a log cabin-style house in East Patchogue, 50 miles east of Manhattan on Long Island. They spent their working lives running a landscaping business. Alexander (who was given the middle name Adolf) lives a few miles away and retired several years ago after a career as a social worker, assisting Vietnam War veterans.

Their father William Patrick Hitler was the British-born son of Adolf Hitler’s half-brother, Alois. Known as Willy, he moved to America in 1939 with his mother Bridget, an Irishwoman who left Alois because he was violent.
