In the journal of his travels in the South, particularly among the Chickamauga, John Norton reported several encounters with the Glass.
Norton wrote that a few years after the Treaty of Paris in 1783, the old warrior traveled up to the North country among the Iroquois and became friends with Joseph Brant, the Mohawk, who was the head chief of the Six Nations and had the same year as the treaty initiated the formation of the Western Confederacy to resist American incursions into the Old Northwest.
Following the assassination of Doublehead in 1809, the Glass succeeded him as head of the Lower Towns' council and was considered their principal chief.
Because Black Fox was acknowledged to be the lawful principal chief of the Cherokee Nation, the local position, along with the Lower Towns' council, was disbanded the next year.
