Roy Blackmore believes that he has compiled the largest documented family tree in the world.
He has spent around £20,000 and five hours a day for the past 28 years scouring archives, cemetery records and census registers to trace his roots back 1,500 years.
He has now traced and listed 9,390 ancestors and applied to the Guinness Book of Records for the title of the world's largest documented family tree.
Experts say his study is "unique" because most of his research was carried out before the birth of the internet - meaning he had to follow a paper trail. [Link]
