William Glass, Sr was born 1725 in Dunkineillly, Donegal County, Ireland, and died 1811 in Leesburg, Washington County, Tennessee. He joined the Colonial armies in the west and was at the Battle of Brandywine in 1777. He was discharged from the army in 1779. During the war he moved to Washington County in Western North Carolina (now eastern Tennessee), with his family and settled at or near where the village of Leesburg now stands. He again joined the army under General Shelby and was wounded in the Battle of King’s Mountain, by a musket over the right eye. It was this engagement that the British General Ferguson was killed. William returned home in 1781.
