Collin County was created from Fannin County in 1846. It was named for pioneer area settler Collin McKinney (1766-1861), a signer of the Texas Declaration of Independence. The first county seat was established at Buckner (2 mi. NW). In 1848 William and Margaret Davis conveyed 120 acres of land at this site for a more central seat of government, which became the community of McKinney. The first two courthouse in the new town were built of wood. In 1874 county commissioners approved plans for a more substantial courthouse on this site. Sherman architect Charles Wheeler designed the building and O.J. King served as general contractor. Constructed of stone from a local quarry (3.5 mi.ne), it was completed in 1876. A grand ball was held in the courthouse to celebrate the event. By the 1920s the courthouse was inadequate to meet the needs of a growing county. Extensive changes, including the addition of a basement and a third floor, were made in 1926-27 under the direction of architect W.A. Peters of Paris, Texas. The site of many political speeches and events, the building was used as a courthouse until 1979. It now serves as a historic reminder of the county's early development.** (1982)***
