I am researching the following surnames in Knox County: Cheuvront, Chapin, Rouse, Shotdell, McCuen, Lutz, Jones, Lawless, and Bieler (Beiler,Biler,Beeler). They lived in the county from 1850 until about 1860. Most of these families moved on to Mt. Plesant and Marion, Iowa; Missouri; and finally Cass County, Nebraska.
