Thomas C. Moore, planter and member of the Secession Convention, was born in Tennessee about 1816. He moved to Alabama with his parents as a child and attended school in La Grange, Kentucky, where he was a classmate and friend of Jefferson Davis. At the age of eighteen he married Martha Hollis of South Carolina; they became the parents of nine children. At some time Moore moved to Mississippi and became a planter on the Tombigbee River near Aberdeen.
He made a visit to Texas about 1846 and in 1851 moved to Bastrop, where he established himself as a planter and merchant. In 1853 he was a trustee of Bastrop Academy. Moore moved from Bastrop to West Point, Fayette County, about 1855 or 1857. By 1860 he had acquired thirty-five slaves and 1,925 acres (575 of them improved). His real property that year was worth $25,000 and his personal property, $40,000. In 1861 he was elected to the Secession Convention, where he voted for secession. In the Civil War he served as captain of the Plum Grove Rifles, a reserve training unit organized on July 8, 1861, as a part of Battalion A, Twenty-second Texas Brigade. An accident he suffered during the war years resulted in blindness. Moore died at West Point in 1897.
