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.
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?)
