Mary Patton first began manufacturing gunpowder with her husband, John, in Cumberland County, Pennsylvania, in the mid-18th century. Eventually, this entrepreneurial couple moved to what is now Northeast Tennessee and opened a new powder mill on Powder Branch in Carter County.
Mary earned her place in history by manufacturing over 500 pounds of gunpowder for the Overmountain Men as they passed through this area on their way to victory at the Battle of Kings Mountain in October 1780.
