Irvin McDougle (1833-1885) was an American soldier who served in the Confederate States Army's 12th Texas Infantry Regiment during the American Civil War. Born in Red Bay, Alabama, the son of Garvin McDougle, he was raised in Nacogdoches, Texas. He enlisted in the Confederate military at the start of the Civil War and fought in the Red River Campaign and the Battle of Jenkins' Ferry in 1864 before being mustered out at the end of the war. McDougle, who shared his Jacobite-descended family's rebellious streak, refused to accept a Union pardon at the end of the war, as he refused to pledge allegiance to the federal government. Instead, he traveled into Mexico in a failed attempt to join up with Confederate remnants in the region. After finding work as a coal miner in Coahuila, he ultimately returned to America in 1873, settling in Silver City, New Mexico. There, he worked as a silver miner until his death in a mining accident in 1885. McDougle had abandoned his Texan family during the Civil War, leaving behind a wife and three sons, including Wes McDougle.
