From Harriet Taylor Upton, A Twentieth Century History of Trumbull County, Ohio, A Narrative Account of its Historical Progress, Its People, and Its Principal Interests (Chicago: Lewis Publishing Company, 1909), Volume 2, p. 192:
CHARLES SEYMOUR GREENWOOD, who is one of the industrious and prosperous farmers tilling the soil within the limits of that goodly agricultural district known as Vienna township, was born in this township, February 5, 1843, a son of Stephen W. and Hepsabeth (Norton) Greenwood. The father was born in Stockbridge, Connecticut, in 1812, and went west with his parents when yet quite small. When grown to manhood he became the owner of a farm in Vienna township. When first purchased it had but two acres cleared up fit for cultivation, but he made an excellent place of it by that work which is always required to make farms within the forest land. Here he resided until death, and here all of his children were born. In this family there were six children: Lomira, deceased; Carlos, deceased; Charles; Corydon, deceased; Rose, now an invalid, residing with her sister Mrs. Andrews.
Charles S. Greenwood obtained a common school education at Woodford’s Corners and Tyrrell Hill. He continued to reside at home with his parents until his marriage, having worked for his father in operating the farm. When he married he bought fifty acres of land, upon which he now resides, going in debt two thousand dollars. He was a partner with his father and brother in a saw mill, which he operated in connection with his farm for about twenty years. He added to his land until he had one hundred and twenty acres, upon which he has made all necessary improvements, his place being considered one of the best in the township. He is a member of the Methodist church, fraternally a Mason, while in politics he is a Republican.
Mr. Greenwood was married November 22, 1868, to Rachel M. Mackey, a native of Vienna township, born April 7, 1841, a daughter of Andrew and Mary (Bartholomew) Mackey. Her father was a farmer, spending his entire life within Vienna township. Mrs. Greenwood died March 2, 1901. She was the mother of the following children: Archie, married Marie Cunningham, resides with the father; Ira M.; Mabel, died in infancy; May, wife of Claud Rhodes, of Fowler township, a railroad man; Remi, residing with the father.
