Tom Blue (died 1910) was an enslaved personal servant and coachman of Sam Houston, who purchased Blue prior to his marriage to Margaret Lea. He worked for Houston for nearly 30 years. In the fall of 1862, he ran away with another servant, a boy named Walter Hume. They traveled together to Laredo, Texas and Blue sold Hume for $800. He crossed into Mexico, where he lived as a free man. Blue later settled in Harrisburg, where he married a woman who was around age 30. He said at the time that he was 119.
