It’s Kansas, and I believe our man was:
William Hamilton Mitchel
“ Born in Foxcraft, Maine. Son of Joshua Mitchell.
Married to Keziah Leland (McLanathan) in 1834 in Maine.
William was a farmer. He was reared on the paternal farm in Maine until 1843, when he located to Lowell, Massachusetts, and served for 10 years as captain of the night police force of Lowell. In 1853, he migrated westward to Galesburg, Illinois, and owned a farm in Knox county, which he developed and cultivated until October 1858. In that year he loaded all of his children excepting the oldest girl, drove over land to Nemaha County, Kansas, locating on the present town site of Centralia. He built a log cabin, but did not live long enough to develop his Kansas farm, death intervening in February 1859 in Kansas. Ten years after William H Mitchell preempted his farm, the town of Centralia was laid out and built on the site of his former home.”
