It all started with an email from a dairy farmer living on a kibbutz in Israel to Esquire Magazine's editor at large, AJ Jacobs. The farmer claimed he was Jacob's 8th cousin. The email sent Jacobs on a three year quest to troll through growing databases and take DNA tests, joining the millions of people obsessed with genealogy.
Jacobs discovers how we are all more connected than we think. His new book is called It's All Relative: Adventures Up And Down The World's Family Tree.
