From the 1885 History of Steuben County, Indiana
Alonzo P. Clark, M. D.,was born at Pratt's Hollow, Madison Co., N. Y., Dec. 23, 1807; his father was a native of Cape Cod, Mass., and emigrated with his wife to Chenango County, N. Y., in 1799. He and his wife were descendants of the earliest New England stock. Dr. Alonzo Clark, when a boy, removed with his parents to Ontario County, N. Y. He early directed his attention to the study of medicine, and began the practice of his profession in 1831, at Port Gibson, Ontario Co., N. Y. He was married October, 1828, in Madison County, to Betsey Bump, who was born in that county Jan. 14, 1808. In the spring of 1836 Dr. Clark came to Steuben County and bought a mill-site and saw-mill in Jackson Township. He also bought a tract of land, a part of which composes the farm of his son Omar and on which was located the original plat of Steubenville. He brought his family later in the season of the same year. He was the first physician in Steuben Township, and perhaps the first in the county. He was a man highly respected, and an excellent physician, and one of the most energetic and progressive of Steuben's pioneers. He died Feb. 3, 1867. Politically he was originally a Whig, and later a Republican. He also practiced law in the early history of the county, and served a term in the Legislature of the State, and was a public speaker of much ability. His wife died March 26, 1878. Dr. Clark had six children, three of whom are living.
