History
Formed in 1855 from Allen County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Marion was created by Kansas Territory in 1855 but remained unorganized and attached to Allen County for judicial purposes. Over the following decade, Marion's boundaries changed repeatedly as other counties were created from its territory and its attachments shifted among neighboring counties. In 1865, Marion absorbed the county of Peketon, and in 1865 it became fully organized and independent.
