Excerpts from the History of Hancock County, Illinois, by Thomas Gregg, 1880:

The earliest settler in the township is supposed to have been Ute Perkins, who came in 1826. The next was John Brewer, in 1827; followed by Abram, James and Mordecai Lincoln, Benjamin Mudd, John Day, Andrew and Pittillo Perkins and Wm. Saylors, all in or about 1830.  Then Wm. Duff, Jabez A. Beebe and Jonathan Prior, 1831; Stephen G. Ferris, 1832; Amos Hobart, 1833; Wm. Allton, 1834; Jary White, 1835; Martin Hopkins, 1836; Col. Thomas Geddes, 1836; David Allton, 1836.
