Josiah Hopkins, D.D. (1785-1862), “a Presbyterian minister, born at Pittsford, Vermont…He never attended college, though he had a good academical education. He was licensed by the Paulet Congregational Association in 1809, and was ordained pastor of the Congregational Church in New Haven, Vt., in 1811. He subsequently became pastor of the Presbyterian Church in Auburn, N.Y.” – M’Clintock & Strong.
Rev. Hopkins spent some time in Ohio as a Home Missionary, afterwards returning to New York and serving Presbyterian churches in Seneca Falls and at Union Springs. “Dr. Hopkins was earnest in his love of the truth, and his perceptions of it were clear and discriminating, his explanations harmonious, and his defence of it most hearty and faithful. He was often sought as a counselor by others, while his genial and kindly spirit endeared him to all who approached him.” – Nevin, Presbyterian Encyclopedia.
