The society evolved from various family groups derived from the 1772 "Scotchfort" and the 1811-1812 "Selkirk" settlers, and others; which were incorporated as a chapter of the newly-formed Clan MacMillan Society of North America in 1958. It became a separate society in 1994. The membership in June 2000 was about 100.
