The New York Times ran a story -- on June 15, 1874 -- about the history of Universalism in that city, which can be read as a PDF in the newspaper's archives. Interesting stuff, including the intersection of radical Universalist minister Abner Kneeland with Tammany Hall -- the building, at least. Indeed, in the telling of the fortunes of the various Universalist congregations, the interplay of who-had-what-building-when suggests a story as yet untold. Lacunae for a history scholar, no doubt. Hint, hint.
The Dr. Chapin mentioned in the title is Edwin Hubble Chapin, whose most famous pastorate was with the Fourth Universalist Society, the last surviving Universalist church in Manhattan.
