The Mystery of Union Lodge No. __
Very little is known about Union Lodge No. __ other than that it appears to have originated in the 1760s, likely having been chartered by a European Grand Lodge or one of several Provincial Grand Lodges then operating in the Colonies. Tradition holds that this grand body was the Grand Lodge of Scotland, but to date no evidence has been found to support that claim.
In the few documents where Union Lodge is referenced, it is not given a Lodge number. This is curious, as Lodges established in the Colonies by European Grand Lodges during the 1730s-1760s were normally given numbers from those Grand Lodges.
Much more research remains to be done on the origin and history of Union Lodge.
