Sylvester Hainline, son of Henry and Nancy (Darnall) Hainline, was born in Boone County. Ky., December 18, 1821, and came to Tazewell County six years later (1827). He was educated in the common schools and remained on the home farm until he was about twenty-two years old, when he began his independent career. Originally he entered 80 acres of land, and later purchased 40 acres in Section 10, where he engaged in farming and stockraising, continuing in that line of industry to the present time.
The paternal grandparents of Mr. Mainline were George and Hannah Hainline. His father, Henry Hainline, was a native of Virginia. He lived for a time in Kentucky, and located in Tazewell County in 1827, where he engaged in farming. At the outbreak of the Black Hawk War, he enlisted as a private and rendered faithful service.
Sylvester Hainline, our subject, was married in Tazewell County, July 20, 1843, to Miss Anna Forbes, born in Ohio, December 6, 1826. Six children were born of this union; Angeline, deceased; Elias, who was killed in the Civil War; Alonzo, who died In Kansas; Melissa, Emma and Ella, the last named being deceased. Mrs. Hainline died February 27, 1856.
Mr. Hainline’s second wife was Miss Elizabeth Hieronymus, a daughter of Harry Hieronymus, who was born in Boone County, Ky., whence he removed to Missouri and there died. Of this marriage four children were born: Jesse H., who is in Montana; Lucy R., who lives in Iowa; Fred H., and Polly M. The daughter last named married William DeLong as her first husband. Her second husband is William Kampf, and by the two marriages she is the mother of five children, namely: Hazel De Long, Clive O. De Long, Dora M. De Long, Avice Karnpf and Gitona Kampf.
