The Third Universalist Church was organized in 1843, and the edifice known as Barristers' Hall was built for its use. It was disbanded after a few years. The pastors were the Reverend H.G. Smith, the Reverend John Moore, the Reverend H.G. Smith, and the Reverend L.J. Fletcher. The Central Methodist Church occupied the edifice for a time, before they secured the building of the Third Baptist Society. The Society was gathered in 1854. The pastors have been the Reverend William S. Studley, the Reverend Isaac S. Cushman, the Reverend Isaac J.P. Collyer, the Reverend Chester Field, the Reverend Lorenzo R. Thayer, the Reverend J.H. Mansfield, the Reverend Andrew McKeown, in 1865 and 1866, the Reverend William C. High, in 1867. The Reverend Isaac H. Packard is the present pastor.
In 1850, a Unitarian Society, organized in 1846, built the Gothic Chapel on Lee Street, and occupied it until 1861, when it passed into the hands of a society of Spiritualists. The Unitarian pastors were the Reverend M.A.H. Niles, the Reverend William Barry, the Reverend Augustus Woodbury, the Reverend J.K. Karcher, the Reverend John B. Willard, and the Reverend William C. Tenney. It became the property of the St. Joseph (French) Roman Catholic Church.
On July 5, 1855, the stone church on Merrimack Street was dedicated as a Methodist Protestant Church. There preached the Reverend William Marks, the Reverend Richard H. Dorr, and the Reverend Robert Crossley. The building passed into possession of the Second Advent Society, which had been organized as early as 1842.
