FLANAGAN, TEXAS. Flanagan, four miles northwest of Tatum and twenty-one miles northeast of Henderson in northeastern Rusk County, was named for David Webster Flanagan, Confederate soldier and Republican politician. The community was established in 1882 as a station on the Longview and Sabine Valley Railway. John Kroeger was postmaster when a post office opened there in 1900. That year the population was recorded as fifty, and the community was known as a shipping point for lumber. Although population estimates for the community reached 200 by 1914, its post office was discontinued in 1916. As of 1950 the town had a predominantly black population. The community was not labeled on the 1982 county highway map.
