Western States Historical Marriage Index
For nearly three decades, the BYU-I (formerly Ricks College) Arthur Porter Special Collections area of the David O. McKay Library in Rexburg, Idaho has been extracting early marriage records from counties in the western part of the United States. This extraction is called the Western States Marriage Index.
Most of the pre-1900 marriages are included in the index for Arizona, Idaho and Nevada. Many counties for those same states have been extracted into the 1930s and some, much later. A significant number of marriages from selected counties in California, western Colorado, Montana, Oregon, Utah, eastern Washington, and Wyoming are also included. Very early marriages (1700s) in New Mexico are currently being added. For more details, see "List of Counties by State". As of November 19, 2020, this file contains over 913,340 marriage records with additional entries being added nearly every working day.Open Resource
