DARGAN, TEXAS. Dargan, a post office community seven miles northeast of DeBerry in northeastern Panola County near the Louisiana state line, was probably established in the early 1880s. A post office opened there in 1888, and in the early 1890s the settlement had a general store, a lumberyard, and an estimated population of fifty. Its post office closed in 1908, and local mail was sent to Bethany, Louisiana. By the mid-1930s Dargan was no longer shown on county highway maps.
