Cumby
Cumby, on the Louisiana, Arkansas and Texas track a half mile north of Interstate Highway 30 in western Hopkins County, was settled in 1842 by D. W. (Wash) Cole. It was named Black Jack Grove because of its location near a grove of blackjack oak trees. The oak grove, just west of the present-day business district, was used as a camp by Texas Rangers during the days of the Republic of Texas. Freight wagoners traveling on the Jefferson road to the interior also used the grove as a campground. The Black Jack Grove post office opened in 1848 in the home of the first postmaster, John D. Matthews. Three years later D. W. Cole bought the grove from Elizabeth M. Wren as part of a tract of 307 acres. Cole ran a store, sold town lots, and donated land for a Masonic lodge that was chartered in 1852. In February 1857 the Black Jack post office was renamed Theodocias, and James M. Brown was postmaster. In May 1858 the post office again became Black Jack Grove.
