No, it's an American series, originally on NBC, now on TLC. Just a short summer show. I looked all I see are some clips, not full versions. It does look like maybe there is/was a British version. Stars searching their family history, but it's amazing what they find and how much history it teaches. Like Chris O'Donnell found one of his great (not sure what number great) grandfather's swords used in I believe it was Mexican American war, stored in the Smithsonian. And then he found out one of his great's fought in War of 1812 and was in Baltimore at the battle that Francis Scott Key was watching from a boat on the water. A lot of interesting facts.
