I sometimes find nice Universalist bits in local histories, but in this history of Sutton, New Hampshire, you get an extended passage on the long-extinct Universalist society (think: parish) there, with organizing documents and a profession of faith.
The history of Sutton, New Hampshire: consisting of the historical collections of Erastus Wadleigh, Esq., and A. H. Worthen (1890)
And speaking of extinct, there is on page 175 this chilling note in the chapter “Casualties and Sudden Deaths”:
Rev. Thompson Barron, a Universalist minister of Newport, N.H., was found dead at the home of Jacob Nelson, about twenty years ago.
That’s all it says. What a mystery!
And that chapter. Gotta love local history.
(His 1871 obituary, reprinted at uudb.orc, is more detailed but still harrowing. Perhaps a heart attack or stroke?)
