Paso Robles, CA -- Their political party lines maybe different but one thing United States presidents could share is their family line.
A young girl in California has put together a Presidential Family Tree. Twelve-year-old BridgeAnne d'Avignon found that all the presidents but one are related to King John of England through a common ancestor.
"They are all cousins and all grandsons of John Lackland," BridgeAnne told KCOY News. The girl searched more than a half million names for months. She started with George Washington, then traced both the male and female family lines to make the connection.
KCOY reports that before this, historians were only able to link 22 presidential family trees.
The teen also found out that she is the 18th cousin of President Barack Obama. She even wrote him a letter to let him know.
The only president not linked to King John: the eight president, Martin Van Buren.
