The Olmsted County Genealogical Society started with a group of people interested in tracing their family trees who met in 1965 at the local Historical Society. In 1976 the Society sponsored a workshop held at the LDS Church in Rochester as a bicentennial celebration. The first newsletter was published in 1977 and has continued since then to share and celebrate family history research, locally and beyond.
OCGS members have made substantial contributions over decades to the collection at the Research Library at the History Center of Olmsted County in Rochester. Volunteers have helped to transcribe and archive historical records, and have raised funds to purchase equipment. OCGS volunteers compiled tombstone inscriptions in every cemetery in Olmsted County, and the information was published in 6 volumes.
Members continue to enjoy meetings from April through November annually to enjoy comaraderie and learn about new resources online, through libraries, and through other members and speakers from the local area and beyond.
