Abbot, Abiel D.D., a Unitarian minister, born in Wilton, N. H., Dec. 14, 1765. He graduated at Harvard, 1787, was assistant in the Phillips Andover Academy from 1787 to 1789, and became pastor of Coventry, Conn., 1795. Having been brought up a Trinitarian Calvinist, Mr. Abbot became, 1792, a decided anti-Trinitarian, and, in 1811, was deposed by the Consociation of Tolland County from the ministry on account of heretical doctrines. From Sept. 1811 to 1819, he had charge of Dummer Academy, and from 1827 to 1839 he was pastor of Peterborough, N. H. He received the degree of D.D. from Harvard in 1838, and died Dec. 31, 1859. He published in 1811 a "Statement of the Proceedings in his Church at Coventry which terminated in his Removal," and some occasional pamphlets. — Sprague, Unitarian Pulpit, p. 229 sq.
