In 1855, Walter C. Willson came to Newcastle. Willson was elected to the Iowa State House the next year and, with John F. Duncombe, crafted a bill to divide the very large Webster County in half. Newcastle would be renamed "Webster City," and would become the county seat of the new county. Willson suggested "Hamilton County" after The Hon. William W. Hamilton, the president of the State Senate who helped pass the legislation. The law took effect on January 1, 1857, giving birth to both Webster City and Hamilton County. Willson was also instrumental in getting the Dubuque & Sioux City rail line to pass through Webster City on to Fort Dodge and personally oversaw the laying of track.GeographyWebster City is located at .According to the United States Census Bureau, the city has a total area of 8.88sqmi, of which, 8.86sqmi is land and 0.02sqmi is water.Demographics2010 censusAs of the census of 2010, there were 8,070 people, 3,433 households, and 2,096 families residing in the city.
