and petitions
for the years 1877 to 1952 for the U.S. District Courts of Denver, Pueblo, Del Norte, and Montrose. The U.S. District Court in Denver has an index to naturalizations granted in these courts since 1876.
The Family History Library has microfilms of U.S. District Courts Naturalization Records for Denver (1877-1952) and Pueblo for the years (1906-1949).

VITAL RECORDS
Births
and Deaths
A law was passed in 1876 requiring counties and towns to record births and deaths. In those counties where the clerks complied, the records are available at the local courthouse. Most early files are incomplete.
Statewide registration began in 1907 and was generally complied with by 1920. Some of the earlier county records and delayed registrations of births
since 1941 are at the Colorado Department of Health. To obtain copies of these records, write to:
Vital Records Section
Colorado Department of Health
4300 Cherry Creek Drive South
Denver, CO 80222-1530
Telephone: 303-756-4464
The current fees for obtaining copies of the state's records are listed in Where to Write for Vital Records: Births, Deaths, Marriages, and Divorces (Hyattsville, Md.: U.S. Department of Health and Human Services, March 1993, FHL book 973 V24wv). Copies of this booklet are at the Family History Library and Many Family History Centers.
You can also write to the Colorado Department of Health for current information. State your relationship to the individual you want information about and your reason. Certificates are released only to members of the immediate family.
The Family History Library does not have copies of Colorado's civil vital records.
Marriages
Each county has kept marriage records since the date it was organized. A few records date from 1860. You can write to the appropriate county clerk for information.
The Colorado Department of Health has a statewide index to marriages from 1900 to 1939 and from 1975 to the present. (On 106 FHL films beginning with 1690047, years 1900-1939, 1975-1992). They will check the index and then forward the inquiry to the correct county office.
The Colorado Division of State Archives and Public Records also has copies of marriage records for 20 counties, including Denver from 1861 to 1952.
Some county marriage records have been extracted and published. For example, many early marriage records have been published in The Colorado Genealogist (see the “Periodicals” section of this outline). The earliest Denver and Arapahoe County marriage records have recently been published in Marriages of Arapahoe County, Colorado, 1859-1901: Including Territory That Became Adams, Denver, and Other Counties (Denver: Colorado Genealogical Society, 1986; FHL book 978.882, V2m, fiche 6087871).
Divorces
Divorce records are available from the clerk of the district court in the county where the decree was granted. The Colorado Department of Health has a statewide index of divorce records for the years 1900 to 1939 and 1968 to the present. The index identifies the county that granted the divorce. The department of health does not provide certified copies. You can write to the county clerk for copies of the records.
