Wyoming began recording births and deaths in 1909. Very few birth and death records were kept on the county level prior to that time. Most of the early births filed at the state office are delayed birth registrations. When specifics are not known, the officials at the State Department of Health can check the alphabetical index for a desired entry, but an hourly fee will be charged.
Certified copies of birth, marriage, and death certificates for the period after statewide recording are available from the Vital Records Services, Division of Health and Medical Services, State Office Building West, Cheyenne, WY 82002.
Wyoming has been recording marriages and divorces state-wide since 1941. Earlier marriages were recorded by the county clerk in the county were the license was issued. All Wyoming marriage records from 1869 to 1970 are available from the Wyoming State Archives and Historical Department for all Wyoming counties. Early divorce records were kept by the clerk of the district court where the divorce took place.
