The History of Hendricks County (Chicago: Interstate Publishing, 1885)--Guilford Township, pages 624-625
William C. Mills, a prominent old settler of Hendricks County, was born in Wayne County, Ind., at the present site of Economy, May 8, 1816, the second son in the family of eight children of Henry and Hannah (Woodward) Mills, natives of North Carolina, the father born in March, 1780, and the mother Sept. 5, 1790. They moved from their native State to East Tennessee, and thence in 1814 to Indiana. They located near Richmond, and then moved to Economy, where they lived two years, but not liking Wayne County, returned to Tennessee; subsequently moved again to Wayne County, where they lived till 1829, when they came to Hendricks County and settled on eighty acres of land on the farm now owned by Aaron Mills. The father died in 1833, in Morgan County, Ill., and the mother in 1862, near the same place. Five of their children are still living. Henry Mills was a valuable man in the new settlement. He was a natural mechanic, and handy with all kinds of tools. He was a good penman, and was often called upon to write deeds, contracts, wills, etc. He was a great reader and was well informed on all subjects of general interest. William C. Mills was about thirteen years of age when his parents moved to this county. He received a good education for the early day, but the greater part of his time was spent in assisting on the farm. He remained with his mother till his marriage, and then settled on a tract of land in the woods, on the Lick Fork, where he lived eight years. After clearing and improving his land, he sold it, and subsequently made several changes, and in the fall of 1855 bought the farm of Joseph Moffett, to which he moved in 1856. He owns about 800 acres of land, about 400 acres under cultivation and the rest good pasture land. Mr. Mills has made a specialty of stock-raising, which he has made a successful and lucrative business. He is a shrewd business man, an upright, honest citizen, and merits the success he has achieved. Mr. Mills was married in 1839 to Rebecca Hadley, a native of Randolph County, N.C., born April 3, 1820, daughter of John B. and Elizabeth Hadley, of Morgan County, Ind. They have had a family of ten children, six of whom are living—John H., Charles H., Amos H., Mary E., wife of Wayne Macy, Oliver H., and Aaron H. Mr. and Mrs. Mills are birthright members of the society of Friends.
