Barren was the first post office in the First District, established September 7, 1839, with Isaac Toomey as postmaster. Other First District post offices were Christiana, 1858-1880; Basin Springs, 1858-1905; Naomi, 1881-1905; Fernvale Springs, 1886-1904; Pasadena, 1899-1904; Craigfield, 1892-1906; and Neutral, 1901-1904. In 1880, during a long discussion by a committee of citizens over renaming Christiana, one farmer said, "It's late. If you can't decide, By Jingo, I'm going home," and Jingo was adopted as the new name. The Jingo post office closed in August 1937, when a new post office named Fairview was built on Highway 100, with Tella Mangrum as postmistress. The Jingo post office building was moved to this site in 2006 from its original location on Elrod Road. Triangle School, serving grades 1-10, opened in 1939 with 115 students, replacing Union Valley School. Its 3.3-acre triangular lot was purchased from W.F. Daugherty for $166.66, and B.B. Sweeney built the school for $2,183.84. Nelle Walker Sullivan, who taught school for 50 years, was the first principal, and Madeline Sullivan Wallace and Ila Thompson completed the original faculty. Other notable teachers were Vella Sullivan Pegram, Ora Givens, Blanche Waters, Carl Walker, Sr., Era Walker, Dora Green, Beulah Page, Ralph Boyd, Othel Sullivan, Ludie Spicer, Mildred McReynolds, DeWitt Fox, and Jesse Frank. An adjacent building served as the cafeteria and canning facility. Fairview Elementary School, serving grades 1-8, opened in 1962 through the merger of Triangle, New Hope, and Fairview Schools.
