The town of Dunnigan was founded as Antelope by two early settlers, J. S. Copp and Jolin Wilson. During the year 1853 they were living down nearer the Sacramento River, but the winter flood washed them on to higher ground and they settled on new claims here. Next year, A. W. Dunnigan came and gave name to the place. With him were Henry Yarick and Abial Barker, the former going into the hotel business with Dunnigan, the inn being known as "Dunnigan's." Other neighbors were Irving W. and William Brownell, Isaac Rice, D. T. Bird, Harry Porterfield and M. A. Rahm. The first store was opened in 1866 by G. B. Lewis, who sold out to William Earll. Z. J. Brown was the proprietor of a drug and notion store for several years, after which he was succeeded by G. W. Gray. In 1876 the railroad came along, and the town plat of Dunnigan was filed for record at the county seat November 1 of that year.[3]

A post office opened in 1856, the name was changed from Antelope to Dunnigan in 1876.[4]
