NELSON SMITH, sawyer and farmer; P. 0. Bucyrus; was born Feb. 7, 1844, in this township. He is the son of Thomas and Mirilla (Ketchum) Smith, who came here young, and, after they were married, located near where Mr. Smith lives. Our subject is the seventh of a family of nine children, who are all deceased, except himself and one brother. His parents were among the first settlers of the county, and knew well the hardship which pioneer life subjected them to. Both died on the same farm, where they first began for themselves, the mother in 1853, and his father five years later. Nelson worked on his father's farm until he was 27 years of age, except one year in which he worked at the carpenter's trade. On Nov. 29, 1866, he cast his lot with that of Cornelia Hise, who was born in this township Feb. 27, 1846. They have two children—Willie F. and Nellie "B. In 1870, he purchased and erected a good saw-mill on his premises, which he has run ever since, doing a good deal of work. He owns 20 acres of land in connection with his mill, which makes them a comfortable home, and which he has made by his own industry. He is a member of Liberty Lodge, Knights of Honor. No. 845.
