Andrew Neill, lawyer and soldier, was born at Lochfergus farm, Ayrshire, Scotland, on January 8, 1813, the son of John and Margaret (Fergusson) Neill. In his youth he immigrated to Willsburg, West Virginia, where he studied law. He was living in Mississippi and had become a probate judge before 1836, when he moved to Texas as captain of a company of volunteers under Felix Huston. Although his group arrived after the battle of San Jacinto, Neill served in the army until 1837. He practiced law for a brief time in Gonzales and then moved to Seguin, where he was an original shareholder in the town laid out in 1838. He participated in various Indian campaigns and took part in the expedition to repulse Rafael Vásquez from San Antonio in March 1842. While trying a case in district court in San Antonio in the fall of 1842, he was captured by Adrián Woll and taken as a prisoner to Mexico. Because he was a British subject, Charles Elliot worked for Neill's release, but Neill managed to escape, traveled to Veracruz, sailed for New Orleans, and was back in Texas in January 1843. His account of the capture and imprisonment was dated January 29, 1843. Neill married Agnes Nancy Brown on September 19, 1844. In 1854 he served as grand master of the Masonic Grand Lodge of Texas. He was a candidate for lieutenant governor in 1855 but was defeated in the party primary. During the Civil War he moved to Galveston for service in the Confederate Army as a lieutenant colonel in the First Texas Partisan Rangers commanded by Walter P. Lane. After his wife's death in Galveston in 1867, he married Virginia Wright Chapman on August 5, 1868; they had two children. Neill moved to Austin in 1875 and lived in the Neill-Cochran house. He died on March 26, 1883, and is buried in Oakwood Cemetery.
