Cimarron County Genealogy Records

Cimarron County genealogy records are kept at the courthouse in Boise City, the westernmost county seat in Oklahoma. This is the least populated county in the state, but its records go back to the early 1900s and carry a unique history tied to "No Man's Land" and the Cimarron Territory. The court clerk has marriage, probate, and court records from 1908. The county clerk holds land records from 1904 and military files. Searching genealogy here means working with a small but focused set of records that can reveal ranching families, homesteaders, and Dust Bowl survivors. You can search some records online, but a call or visit to the clerk is often the fastest route.

Cimarron County Genealogy Record Types

Vital records listed through genealogy sites include births from 1908, marriages from 1895, deaths from 1908, land records from 1896, probate records from 1900, and court records from 1896.

No Man's Land and Cimarron County Genealogy

Cimarron County has a history unlike any other county in Oklahoma. Before 1890, this strip of land was called "No Man's Land" because no state or territory claimed it. Settlers arrived anyway. They set up their own government in what they called the Cimarron Territory. Congress eventually added the area to Oklahoma Territory in 1890, and it became Cimarron County at statehood in 1907.

If your ancestors lived here before statehood, records may be scattered. Some are at the county courthouse. Others ended up at the Oklahoma Historical Society or in private collections. The ranching heritage of this area means many families stayed for generations, which can make research easier once you find a starting point.
