Caithness and Sutherland was the home of the Gunns, for whom a Norse origin is claimed. They were frequently engaged in clan warfare and did battle with the Keiths, MacKays and Sutherlands. In an effort to settle their dispute with the Keiths, a meeting was arranged in 1464 between both clans, but the Keiths treacherously attacked the Gunns and slew the chief. This chief, George Gunn, held the office of Crowner and lived in regal style at Clyth Castle. His badge of office as Crowner was a large silver brooch from which he was known as "Am Braiteach Mor". The name comes from the Norse "Gunnar".
