Grayson County is the home of the Historic Jack Thomas House which is owned and maintained by the Grayson County Historical Society. The Jack Thomas House contains a museum dedicated to the history and families of Grayson County as well as the most extensive genealogical research library for the county. It is open Monday – Friday for tours and research. Three general meetings with guest speakers relevant to the county each year are held for the membership. They are held in March, June, and October and are always open to the public. The house is open during the Twin Lakes National Fiddlers Contest (see below), the Hometown Christmas Parade as well as other special events.
