 William Hazlitt (father of the essayist and critic), visiting the United States in 1783–1785, published the fact that there were Unitarians in Philadelphia, Boston, Charleston, Pittsburgh, Hallowell, on Cape Cod, and elsewhere.Unitarian congregations were organized at Portland and Saco in 1792 by Thomas Oxnard; in 1800 the First Church in Plymouth—the congregation founded by the Pilgrims in 1620—accepted the more liberal faith.Joseph Priestley emigrated to the United States in 1794, and organized a Unitarian Church at Northumberland, Pennsylvania, the same year and one at Philadelphia in 1796.
