The group of 102 passengers who crowded aboard Mayflower for the crossing was not homogenous. Many of the passengers were members of the Leiden congregation, but they were joined by a number of English families or individuals who were hoping to better their life situations, or were seeking financial gain. These two general groups have sometimes been referred to as the "saints" and "strangers."

Although the Leiden congregation had sent its strongest members with various skills for establishing the new colony, nearly half of the passengers died the first winter of the "great sickness."

Anyone who arrived in Plymouth on Mayflower and survived the initial hardships is now considered a Pilgrim with no distinction being made on the basis of their original purposes for making the voyage.

Many families hold a tradition that they are descended from the Pilgrims, which often kindles an interest in finding out more. Sometimes the stories of a Mayflower heritage are true and it is easy to document a descent. More often the documentation is missing and must be researched and supplied to prove your line. The good news is it that advanced research techniques, improved genealogy library collections and computerized resources have made it easier to track down your Pilgrim roots.

The Mayflower Pilgrims and their fellow travelers were authors of the first true governing document created in a New World colony. The Mayflower Compact is considered to have set the stage for the Constitution of the United States.
