The Regulators in Ogle County began by whipping two horse thieves, one of whom joined the group after the incident. The first Ogle County Regulator captain, W.S. Wellington, stepped aside after his grist mill was destroyed and his horse tortured and killed in April 1841. The new captain, John Campbell, was a resident of White Rock Township. The local Banditti were the Driscoll family and members of the Driscoll Gang. At the head was John Driscoll, who had migrated from Ohio in 1835 with his four grown sons, William, David, Pierce, and Taylor. The Driscolls lived on Killbuck Creek in northeast Ogle County. Driscoll and his son Taylor had both been convicted of arson while they lived in Ohio.
