Or keep minutes, that we know of.
The Quaker Meetings in Salem, Hampton, and Dover were all in Puritan-governed colonies, and thus officially illegal at the time. Religious toleration around 1680 came with a change New England governance and a royal governorship in Massachusetts.
With it, Salem has claimed to have the first Friends meetinghouse in America, though it was built about the same time as the one on Dover Neck, just south of today’s St. Thomas Aquinas high school. And Third Haven on Maryland’s Eastern Shore may be a tad older than either one.
Now, if we only had documentation, we might find the honor of being first in New England belongs instead to Dover.
