Oklahoma Counties records vary widely from county to county both in quality as well as quantity. Some are already very carefully preserved while others have been much abused and mistreated. Some Oklahoma records have merely vanished. For genealogists carrying out research in Oklahoma there’s no effective substitute for an on-site search of county court house records. For Definitions of all court terms see the Genealogy Encyclopedia

Oklahoma Counties – Oklahoma originally had seven counties when it was first organized as the Oklahoma Territory. These counties were designated numerically, first through seventh. New counties added after this were designated by letters of the alphabet. The first seven counties were later renamed. The Oklahoma Constitutional Convention named all of the counties that were formed when Oklahoma entered statehood in 1907. Only two counties have been formed since then.

Oklahoma is divided into 77 counties. Oklahoma deeds, probates, and civil court records are located at the county clerk’s or clerk of the courts office. Marriage records before statewide recording may be found at the county clerk as well, but records of births and deaths are not available until statewide recording began. Official certificates come from the State Department of Health. The largest percentage of Oklahoma’s extant public records were generated in the twentieth century and are generally intact. Send inquiries to the county official at the courthouse address for the appropriate county. See also a list of links to county and county seat government run websites.

Map of Oklahoma Counties

Oklahoma contains counties that no longer exist. They were organized by the state, provincial, or territorial governing administration. Many of these counties were created and disbanded in the 19th century; county boundaries have changed little since Nineteen hundred in the great majority of states. These counties need to be researched when performing ancestors and family history research. Pay attention where the courthouse records went to if the county was eliminated or merged with a different county.

The destruction to Oklahoma courthouses drastically has a affect on genealogists in almost every way. Not only are these kinds of historic structures ripped from our lifetimes, so are the documents they stored: marriage, wills, probate, land records, among others. Once destroyed they are lost permanently. Although they have been put on mircofilm, computers and film burn as well. The most heartbreaking aspect of this is the reason that almost all of our courthouses are destroyed as a result of arsonist. Though, don’t assume all records were destroyed. Numerous Oklahoma counties have suffered a loss of records due to courthouse fires, floods, and theft.
