The website identifies 108 passengers and crew members known to have left descendants, allowing participants to locate their Pilgrim relative. Those who are a known descendant of a Pilgrim can post their story on the website.

The new project will help mark the 400th anniversary of the Mayflower's passage, which takes place in 2020, The Associated Press reported.
