New England Historic Genealogical Society and General Society of Mayflower Descendants Announce Database Collaboration

New England Historic Genealogical Society (NEHGS) has partnered with General Society of Mayflower Descendants (GSMD) to bring new searchable databases created from authenticated Mayflower Pilgrim genealogies and from 50 years of published Mayflower passenger scholarship from the Mayflower Quarterly. GSMD members will enjoy generous discounts on new memberships in New England Historic Genealogical Society, the founding genealogical organization in America.

Known as the "Silver Books" because of their distinctive covers, the Mayflower Families Through Five Generations series from the General Society of Mayflower Descendants meticulously documents the first five generations of descendants of Mayflower passengers who arrived in 1620. This essential resource has previously been accessible only in print format. As a result of this partnership, the fifth generation portion of these will be available online on for use in family history research by members of both organizations.

The "Silver Books" series is comprised of 31 volumes, of which the fifth generation of each will be brought online as a database as the digitization is completed. 50 passengers on the Mayflower are known to have living descendants, however, the “Silver Books” treat the 25 families that left American descendants.

Partnership to Include Digital Indexing of Mayflower Quarterly

As an important additional element of the historic partnership between the two organizations, NEHGS will also undertake indexing of content published in the first fifty years of the Mayflower Quarterly—A Journal of Pilgrim History and Genealogy in Colonial New England. GSMD published this predecessor to the current Mayflower Journal from 1935 through 2015. Fifty volumes of the Quarterly, those issues published between 1935 and 1984—Volumes 1 through 50—are to be indexed by article title and by the names included in them. They will be made available as page images on

Updates concerning availability of these new databases to be offered exclusively by NEHGS may be found in announcements in the weekly e-newsletter of NEHGS, The Weekly Genealogist, or by registering at

Membership Benefits

NEHGS and GSMD are both member-based organizations. Benefits of discounted annual membership subscription fees will be offered by NEHGS to all active members of GSMD, as the two entities collaborate on these historic projects. With a growing collection of more than one billion online records on its website, original scholarship, and unique educational resources, NEHGS offers tools and expertise needed to uncover and document the many Mayflower Pilgrim and related ancestral stories that the GSMD has diligently celebrated for more than 100 years. Its commitment to research on the lineal descent of the Mayflower Pilgrims and to education about them— how they shaped western civilization, and what their 1620 voyage means today—will be advanced through this new partnership with NEHGS and its more than 220,000 constituents worldwide.

We expect this part to begin during the summer of 2017. The entire “Silver Books” project will be completed sometime in 2018. The Mayflower Quarterly indexing work will start after the “Silver Books” are completed. This portion of the project is expected to take up to 18 months to complete.
