Actor Benedict Cumberbatch's connection to Sherlock Holmes has been proven to be more than just his role on the popular British TV series "Sherlock."
Researchers at Ancestry.com put on their deerstalker detective hats and found clues that revealed Cumberbatch and Sherlock Holmes creator Sir Arthur Conan Doyle are 16th cousins, twice removed.
Cumberbatch and Doyle are connected by their common ancestor John of Gaunt who was the duke of Lancaster and the fourth son of King Edward III of England, who lived in the 14th Century, the website said.
"Making family history connections is similar to piecing together a mysterious puzzle, one that the great Sherlock Holmes himself would be intrigued to solve," said Ancestory.com family historian Lisa Elzey.
