was the first white settler in the county. In the summer of 1822, after realizing there were enough settlers in the area, Conner and other settlers applied to the Indiana Legislature for a charter authorizing them to become a separate and independent county under Indiana law. The application was presented to the 1822–23 session of the

Most Belgian immigration to Indiana occurred in the northwestern part of the state in Lake County and Porter County. However, in the 1890s, a significant number of Belgian immigrants also settled in the Noblesville area of Hamilton County. Similarly, chain migration led to numerous first generation Serbian immigrants who had settled in Indianapolis, and their Indiana-born children, to move to Arcadia, Carmel, Sheridan, Noblesville, and Cicero around the turn of the 20th century.

, Hamilton County was noted for an extreme rise in anti-German sentiment. The name of Wilhelm Street in Noblesville was changed to Washington Street and German-Americans were subjected to bullying and abuse from their neighbors. German-Americans were one of the largest ethnic groups in the county, but the remaining two-thirds of the county were "whipped into an anti-German frenzy" during which Germanness and Americanness were presented as being antithetical throughout the press. Hamilton County was labeled the "most anti-German county" in Indiana, although such attitudes were common throughout the rest of Indiana as well. During most of 1940 and 1941, Indiana as a whole was very isolationist, with much of the state preferring that the country stay neutral in the European conflict. However, Hamilton County was a "hot-bed of interventionist and pro-British sentiment", which stood out because unlike many other places in Indiana, most people in Hamilton County were in favor of American entry into the war, and were in favor of providing Britain with as much aid as possible as well.
