AJ Jacobs made some headlines inside and outside of the genealogy community back in 2014-15 by setting out to have a Global Family Reunion. His mission is to connect everyone in the world to each other in one human family tree. He wrote a bit about it in a NY Times article.
On WikiTree, you can see how you connect to AJ (and many others) using their site since they built it to be one large tree. I recently finally connected my tree to his and no surprise that it was via my French-Canadian line. Once I connected my CLOUTIER ancestors to their father, my connection was complete. Now, this is not a direct “cousin” as we genealogists know it, but just a “degree of relationship” connection. It’s more like six-degrees of Kevin Bacon (whom you can also see if you connect to, I do, too.)
I am 29 degrees from AJ Jacobs, so “I am a cousin!” and I am unfortunately more than six-degrees from Kevin Bacon (27). If you want to know how you connect to them, or even me, start filling in your WikiTree lines. The site is very easy to use.
