High Quality Content by WIKIPEDIA articles! The New England Historic Genealogical Society, also known as NEHGS, is the oldest and largest genealogical society in the United States, founded in 1845. A charitable, nonprofit educational institution, NEHGS is located at 99-101 Newbury Street, in Boston, Massachusetts, in an eight-story archive and research center. Today it has over 24,000 members worldwide and a 50-person staff. Its mission is to "collect, preserve, and interpret materials to document and make accessible the histories of families in America." In 2010, NEHGS announced a broader identity and re-launched its quarterly magazine as American Ancestors: New England, New York, and Beyond to better reflect its national scope and leadership position among genealogical nonprofits.
