A community grew up near Fort Johnson on the Texas Military Road (also known as the Shawnee Trail) in the 1840s. Earlier called Georgetown and Reevesville, the settlement became known as Fink when a post office (500 feet north) was established in 1897 and named for Fredrick Finke (1858-1920), a German immigrant who had come to Grayson County in 1884. The post office was discontinued in 1908. Never incorporated, Fink was eventually included within the boundaries of Pottsboro. In the 1960s local residents began annual Fink celebrations.
