William Ferguson is buried in the cemetery at the Big Spring Presbyterian Church. This church, established in 1738, is still an active congregation and is in Newville, eleven miles west of Carlisle. Ferguson was a carpenter and during the Rev. War he was stationed at the Carlisle Barracks Armory, also known as Washingtonburg. He designed and built the wooden carriages that were used with the William Denning cannons. William Denning is buried in the same cemetery about 200 feet from Ferguson. The church records show that there were seven members in the Ferguson family.
