Born in Blount County, Tennessee, Andrew Jackson Montgomery came to Texas in 1819 with the James Long Expedition. In 1823, as the first known settler in Montgomery County, he opened a trading post at the crossing of two Indian trails. From his post emerged the town of Montgomery, from which Montgomery County took its name. A veteran of the Battle of San Jacinto, Montgomery married Mary Mahulda Farris at age 43, and they had nine children.
