On 7 February 1859, the following daughter counties were created from parts of the old Arapahoe (1855) County, Kansas Territory (never organized, and now in Colorado):^{[1] [2]}

• Arapahoe County, Kansas Territroy (east sides of modern Adams, Arapahoe, and Elbert, and parts of Washington, Lincoln, Crowley, Otero, Bent counties in Colorado)
• Broderick County, Kansas Territory (modern Pueblo County, eastern Fremont and Custer, and southern El Paso counties, Colorado)
• El Paso County, Kansas Territory (northwestern El Paso, southern Douglas and Teller counties, Colorado)
• Fremont County, Kansas Territory (southern Park and Chaffee, Fremont, northern Custer and Saguache counties, Colorado)
• Montana County, Kansas Territory (southern Boulder, Jefferson, Gilpin, Clear Creek, Denver, northern Douglas and Park, western quarters of Arapahoe and Adams counties, Colorado)
• Oro County, Kansas Territory (central Adams, Arapahoe, and Elbert, and northwestern El Paso counties, Colorado)

The old Arapahoe County had been attached to Marshall County, Kansas for county business purposes.^[2]

When Colorado was organized 28 February 1861 its core included all parts of the original (Kansas) Arapahoe County. At that time three daughter counties were replaced, Broderick, Montana, and Oro, and their names were discontinued. The three other daughter counties, Arapahoe, El Paso, and Fremont, remained but with significantly modified borders.^[3]
