Of particular interest in this document are pages 19 and 20, which contain two separate references to an attack on a Cox family and the murder of the wife of one John Wallin, who has been said to be a Mary Cox or Mary Roberts by birth. The former incident was mentioned in a report by the Historical Society of Southwest Virginia in 1968, which serves as an influential source for some details regarding David Chadwell.
