History
Formed in 1855 from Doniphan County and Browne County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Brown County was created by Kansas Territory on August 25, 1855, from non-county area and initially attached to Doniphan County for civil and military purposes; the county name was originally spelled "Browne," but the final "e" was dropped by 1859. The county was fully organized and detached from Doniphan on February 14, 1857, and became a county in the state of Kansas on January 29, 1861. Brown County lost territory to Jackson County on March 1, 1868.
