Allenville was named after Tom Allen, who was the builder of the Belmont Branch Railroad and was platted in 1869 when the railroad was extended to that point.[5][6] The community was also a point on the old Lone Star Trail, and cattle were driven over the trail all the way from Texas to the Allenville railroad terminal. A post office was established at Allenville in 1869, and remained in operation until 1974.[7][8]
