Blair served in the American Revolutionary War as an orderly sergeant, ensign and Indian spy.
He was an express rider who alerted troops of the coming Battle of King's Mountain.
He was wounded, but completed the ride and served with Colonel Benjamin Cleveland during the battle.
He relocated to Pickens County, Alabama, in 1836 and died there 5 days after his wife in 1839.
In 1926, the Daughters of the American Revolution in Corsicana, Texas, paid tribute to Colonel Blair by naming their chapter after him.
