Rosecrans was born on a farm near Little Taylor Run in Kingston Township, Delaware County, Ohio, the second of five sons of Crandall Rosecrans and Jemima Hopkins. (The first child, Chauncey, died in infancy.) Crandall was a veteran of the War of 1812, in which he served as adjutant to General William Henry Harrison, and then subsequently ran a tavern and store as well as a family farm. One of Crandall's heroes, General John Stark, was the inspiration for William's middle name. Rosecrans descended from Harmon Henrik Rosenkrantz, who arrived in New Amsterdam in 1651, but the family name changed spelling during the American Revolutionary War. His mother was the widow of Timothy Hopkins, a relative of Stephen Hopkins, the Colonial Governor of Rhode Island and a signer of the Declaration of Independence.
William had little formal education in his early years, relying heavily on reading books. At the age of 13 he left home to work as a store clerk in Utica, and later Mansfield, Ohio. Unable to afford college, Rosecrans decided to try for an appointment to the United States Military Academy. He interviewed with Congressman Alexander Harper, who had been reserving his appointment for his own son, but was so impressed by Rosecrans that he nominated him instead.
