One World Tree is a beta project of ancestory.com. OneWorldTree gathers family trees and family history records for millions of people, analyzes the birth, death and marriage data and then displays the most probable matches for your ancestors. I've been playing a bit with this and discovered Fabien Thibault has been entered into the tree. I've found probable matches with the following:
Five First Ladies (not including already knowing we are related to Hillary Rodham Clinton)
Margaret Mackall Smith Taylor was the wife of President Zachary Taylor
Martha Jefferson was married to U.S. President Thomas Jefferson
Elizabeth Kortright Monroe was the wife of President James Monroe
Jacqueline Bouvier Kennedy Onassis was the wife of President John F. Kennedy
Laura Bush was the wife of George W. Bush
T.S. Elliot (we are most definitely 6th cousin 4 times removed from Fabien)
Jack Kerouac (3rd cousin 3 times removed from Fabien)
Mary Flannery O'Connor (really very very distant)
A few of inventors
Robert H. Goddard, the father of modern rocketry
Louis Pasteur is famous for "pasteurization," a means of preventing milk from going sour (how appropriate)
Gottlieb Daimler designed and patented the prototype for the modern gas engine.
William Thomson, 1st Baron Kelvin, was an Irish Scottish mathematician and scientist known for his contributions to the studies of thermodynamics and electricity.
A signer of the Constitution
Robert Morris Pennsylvania Representative and 26th Great Grandfather of Fabien (maybe)
Prior to signing The Declaration of Independence, The Constitution, and The Articles of Confederation;
Robert Morris borrowed money to pay Washington's troops during the Revolutionary War.
Joan of Arc
Phillip the Good Duke of Burgundy (July 31, 1396 – June 15, 1467)
Many of these are questionable because of missing people in between supposed links and questionable linkage at best, but others are more reliable because I can trace them in our tree.
