How the Work of a 12-Year-Old Girl Uncovered a Historical Oddity
It started with an American 12-year-old girl’s desire to trace her own heritage back to France. Along the way, she discovered that every single US President (except Martin Van Buren) are relatively closely related to just one man.
Meet BridgeAnne d'Avignon a gifted seventh grade student at Monte Vista School in Watsonville California.
Prior to her work, genealogists only marginally associated about 19 US presidents as “distantly” related. She has created an amazing poster available at her website:

Her work started when she was just 10 years old when she discovered her Grandfather’s genealogy software and challenged herself with a simple question: “How many US Presidents are related?” The answer was an astounding coincidence.
Academic genealogists were more than shocked to discover that this association was in the historical record and overlooked by thousands of researchers. One of the secrets to BridgeAnne’s work was to trace the genealogy of both parents. She was not sure where the journey would lead her to, but pushed on for over two years of research.
Every US President Is Part of One Bloodline
The distant grandfather to all US presidents is King John "Lackland" Plantagenet. The very same King John that was the antagonist to the Robin Hood story.
Update:
I have removed statements about conclusions drawn from her work on the probability of this exact circumstance occurring. This aspect was rather inflammatory to some. I will leave it up to the those interested to seek out this information. It is certain that when you factor out to a 7th cousin mathematically using the Diamond or Pyramid genealogy theory you have millions of people related. Of course, all of us are related, if one were to go far enough back in time. In the 846 years that have passed and the millions of potential outcomes, this to many is fascinating.
