They reared a family of five children—Amos R, John, Harlow, Charles and Mary. The sons removed to Edgar Co., Ill., where they lived until they came to Green county. In the spring of 1836, Amos came here and entered land for his brothers and others, and returned to Illinois. In the fall of that year, the Sylvester brothers, Amos, John, Harlow and Charles, and their families, came here to reside permanently. Amos settled on the northwest quarter of the northwest quarter of section 15, where he erected a log house with a puncheon floor and roof of shakes.

Charles Sylvester settled on the west half of the northeast quarter of section 10, remained there a short time, then sold and went to Belleville, where, in company with John Sylvester, he engaged in mercantile business. He now lives in Polk Co., Wis. Amos R. Sylvester received a common school education, and at the age of seventeen years, left home. He started in the work with fifty cents, which his mother had given him, being all the money she had. He served an apprenticeship to learn the blacksmith trade, and afterwards was foreman in a shop at Camillas, N. Y., where he was married Feb. 14, 1831. His wife died in Sylvester, Aug. 30, 1847, leaving five children—Richard, deceased; Abram W., Henry W., Mary, deceased; and Moses. He was again married to Mrs. Loraine Rust, widow of Henry Ford.
