Thomas Graves came to Texas in 1831 as part of Robertson's Colony (located in present-day Milam County) and worked as a surveyor while waiting for his application for citizenship and land to be approved. Four years later, he finally received his title to one-fourth of a league of land on November 10, 1835. On January 14, 1836, he enlisted in Captain Sterling C. Robertson's Company of Rangers, but the company shortly afterward disbanded. He re-enlisted April 8, 1836 as a member of Captain Jesse Billingsley's Company of Mina Volunteers and was with them at the Battle of San Jacinto. His enlistment ended on July 8, 1836, and he returned to his estate. He married in April 1837, and later that year was elected the first County Surveyor of Milam County. Several years later, for his service in the Texas army and for fighting at the Battle of San Jacinto, he was granted an additional three-fourths of a league and one labor of land near his homestead in Milam County. Graves died in Washington County in 1861 and was buried in the cemetery in Independence.
Note: Graves' burial site is unmarked and its exact location has been lost, but it is likely he is buried somewhere in the photo below where the majority of those who died in 1860-1864 rest.
