General Society of Mayflower Descendants and Research Library

Founded in 1897, The Mayflower Society, or General Society of Mayflower Descendants (GSMD), is a 501(c)(3) non-profit organization. Our national headquarters is on the campus of the historic Mayflower Society House in downtown Plymouth, Massachusetts. Membership requires proof of lineage from one of the passengers who traveled to America on the Mayflower in 1620.

The General Society of Mayflower Descendants, GSMD, tells the story of the Pilgrims’ journey on the Mayflower in 1620, bringing with them principles of civil and religious liberty to America as memorialized in The Mayflower Compact – why they were important, how they have shaped America, and what it means today – so that all generations will understand the Pilgrims’ place in history and be inspired by what they learn.

We operate a genealogy research library at our Plymouth headquarters and publish the GSMD Silver Books, a series of genealogy books that follow the descendants of the Mayflower passengers. For more information about our Research Library Click Here.
