The American Fur Company of John Jacob Astor established a post in the area in 1829. Settlement began in 1833, shortly after the Black Hawk Purchase, when Samuel (aka Simpson) White, Amzi Doolitle, and Morton M. McCarver crossed the Mississippi River from Big Island and staked claims there. According to an account A.T. Andreas wrote in 1875, White erected a cabin in the area later platted to be Front Street between Court and High streets. Andreas called White and Doolittle the Romulus and Remus of their settlement, referring to the mythic heroes who founded Rome, a city surrounded by hills. A few weeks later, William R. Ross joined them and established a general store. In November and December, he surveyed the settlement for White and Doolittle.
