CYRUS MARSHALL, farmer and stock-raiser, P. O. Cranberry, was born in Lawrence County, Penn., June 22, 1826, a son of James Hayes Marshall, a farmer. His parents were natives of Pennsylvania, and of Irish descent. Our subject, the fifth in a family of ten children, was reared on the farm, acquiring a common school education. He was united in marriage, in 1850, with Mary, daughter of Samuel Reed, a native of Mahoning County, Ohio, and of English descent. To this union were born four children: James H. and Margaret Alice (both deceased); John R. (who has been a school teacher, but is now a prominent farmer of this county), and Albert H. (also a farmer), they both graduated from the normal school at Ada, Ohio, are married and own their farms. Mr. and Mrs. Marshall are members of the Presbyterian Church at Rockport, Ohio, which he helped build, has been a member thirty-three years, and is now trustee in same. In politics he is a Republican. Our subject came here by wagon in 1851, and settled in the woods on the farm where he now resides, comprising 150 acres, which his father, who never lived here, however, had previously entered. He put up a cabin, and began clearing his farm, sending the grain he raised to the mill at Delphos. By industry he has accumulated a comfortable competency, and now owns two well-cultivated farms, comprising 160 and 154 acres, respectively. He has been engaged in buying and selling live stock, making a specialty of sheep, and now has 450 head of Spanish merinos.
