Elizabeth Tilley (c. August 1607 – December 21, 1687) was one of the passengers on the historic 1620 voyage of the Mayflower and a participant in the first Thanksgiving in the New World. She was the daughter of Mayflower passenger John Tilley and his wife Joan Hurst and, although she was their youngest child, appears to be the only one who survived the voyage. She went on to marry fellow Mayflower passenger John Howland, with whom she had ten children and 88 grandchildren. Because of their great progeny, she and her husband have millions of living descendants today.
