JAMES W. KILGORE
James W. Kilgore, farmer, Brighton Township, was born in Lee County, Iowa, May 30, 1840, a son of Matthew and Massa (McGuire) Kilgore, the former a native of Ross County, Ohio, the latter also a native of Ohio. Hannah Gilfore, aunt of James W., was the second white child born in that county, namely, where Chillicothe now is, January 18, 1799. Matthew resided in that county until 1827, when he moved to Tippecanoe County, Indiana; in 1837 he removed to Lee County, Iowa, and in 1852 he came to California, by way of Council Bluffs, crossing the Missouri River on the 23d of May and arriving here October 10. He brought his family here in 1852, making both trips across the plains. The second time he was with a large train, starting with thirteen wagons and they were six months on the journey, but had no special trouble. Among the party were George and James Wilson, of Oregon. The family then consisted of five children: George, since deceased; Teresa, who married James Wilson and has since died; Elizabeth, David and James. The eldest son, William, had preceded them to this State in 1850, with his father. They first located in Yolo County, on the Sacramento River, fifteen miles below Sacramento; in the spring of 1853 they moved to Santa Clara County, and in 1855 returned to this county. From 1858 to 1864 they were residents again in Yolo County, and then finally settled in this county. Matthew Kilgore died March 16, 1882, at the age of eighty-one years. His wife died April 8, 1875, at the age of seventy-seven years. Of the family three are now living—David, Elizabeth and James. The latter was twelve years old when he came to this State, and remained with his parents until their death. The home place originally contained 324 acres, of which seventy-seven acres now belong to James in Brighton Township, and eighty acres in Lee Township. Elizabeth married Archibald Criswell, and they have four children: Alice, wife of W. F. Bryan; Martha, William and George, all residents of this county.
