When you think of Thanksgiving, chances are you envision turkey and Pilgrims. At that first Thanksgiving table in 1621, the Pilgrims had much for which to be thankful. They were celebrating a good harvest, but they were also thankful to be alive; of the 102 passengers who survived the treacherous voyage from Plymouth, England to Plymouth Harbor aboard the Mayflower the previous fall, more than half had succumbed to disease. As a result, of those 102 Mayflower passengers, only 29 are known to have descendants. The Mayflower Society, an organization dedicated to the preservation of Pilgrim history, estimates 35 million people are descended from those 29 brave souls. While that number represents some 11 percent of the current U.S. population, only about 25,000 people have been able to trace their lineage back to those brave voyagers and, in turn, qualify to join The Mayflower Society. However, a surprising number of famous people are counted among those descendants.
