The society was formed to bring together as many of the descendants of stockholders in the
Virginia Company of London and the descendants of those who owned land or who had domiciles in
Jamestown or on Jamestown Island prior to the year 1700 as possible. Since its founding, the Society has helped conserve colonial records, financially supported the archaeology dig inside the Memorial Church at Jamestown, paid for the casting of the replica bell, and partnered with Jamestown Rediscovery to publish
Church & State: The Archaeology of the Foundations of Democracy in 2019. The Society also funded the rebuilding of the Barracks Exhibit in 2020, and funded the Eastern Expansion Dig in 2021. The Society has branches, called "Companies." (In the Jamestowne Society, "Companies" are similar to chapters in most lineage societies). Membership in Companies is elective, while membership in the national Society is acquired at the time a member proves descent to a Jamestown Settler or Stockholder. In 1983, the Society was formally organized as a non-profit corporation under section 501(c)(3) of the Internal Revenue Code (1954, as amended). The Society holds annual meetings and events. The Jamestowne Society moved its headquarters to Williamsburg, Virginia on February 7, 2022; the headquarters was previously located in
Richmond, Virginia. Jamestowne Society is listed as an approved lineage society with the
Hereditary Society Community of the United States of America. == Notable members ==
