In 1941 a minister in the Pippin family wrote that they all descend from Charlemagne. A year later he admitted that proving it would be costly, and said family tradition made it too strong to deny. Ruth works the case with a doubling ancestor tree, a 2004 Nature paper on the common ancestry of all living humans, and a study of 2,257 Europeans that separates the ancestors on your family tree from the ancestors in your DNA. Danny defends the Pippins the whole way.
The verdict: probably true, but in a way that is true for almost everyone, and it may have left no trace in your genes. The part of your family history you can actually prove is sitting at your Thanksgiving table. This week, ask your parent which famous ancestor the family claimed, who first told the story, and how they said they knew.
