History Timeline
1879--Cassia County was created 20 February 1879 from Owyhee County. County seat: Burley Albion was the county seat from 1879 until 1919 when the county seat was moved to Burley.
 * Twin Falls County was separated from Cassia County on 21 Feb 1907. Some websites suggest that Power County, which was created in 1913, included some land from Cassia County. This may have been due to boundary corrections.

Some sources list both Owyhee and Oneida Counties as the parent county of Cassia. Owyhee County, the fifth county in the Idaho Territory, was created on 31 December 1863. Oneida was formed on 22 January 1864 Owyhee County included "All territory lying south of the Snake River and east to the range of the Rockies, the southern boundary being the Nevada and Utah State lines. The width of Idaho Territory at its southern boundary was 397 miles. Of this distance, over 300 miles were in Owyhee County." Oneida County bordered Owyhee and Alturus Counties on the east and continued to the territory line. A Cassia County surveyor (November 2008) indicated that he has seen title searches in Cassia County that trace back to Oneida County. He suggested that it was probably due to a boundary correction straightening out the eastern border between Cassia and Oneida rather than large amounts of land taken from Oneida to create Cassia County.

A handwritten statement made sometime after 1917 on the front page of the Cassia County Transcript Book #1 states: "From Page 1 this Book to Page 56 both inclusive contains Instruments transcribed from Owayhee County to November 11, 1878 . Cassia County and Twin Falls County at above date was included in Owayhee County. Cassia County including Twin Falls County at that date was known as Cassia County and was sometime about the first of 1879 set off from Owayhee County to be known as Cassia." Simon P. Weatherman, County recorder, traveled to Silver City, the county seat of Owyhee County, and transcribed all of the Owyhee County records which involved Cassia County residents. A photocopy of the Transcript Book is available to the public at the Recorder's office in the Cassia County Courthouse and the original book has been archived There are shelves of original books containing marriage records, some birth and death records, deeds, mortgages, etc. Court records are also available, though they have been archived and require the county officials to locate them.

The Old Oregon Trail, the California Cutoff, Hudspeth's Trail, the Salt Lake Cutoff and the Applegate Trail all went through the area. It wasn't until the early 1870's, however, that families began to settle here. Early settlers in Almo, Elba and Oakley areas were largely descendants of the Mormon Pioneers. The lands along the Wasatch Front were becoming "crowded" and many families moved northward, congregating along the streams where water was available for irrigation and the native grasses grew in meadows that could be harvested for hay. Branches of The Church of Jesus Christ of Latter-day Saints were created, schools established, and a few stores The stage and freight trains passed through the Albion valley, and in the 1870's, some travelers decided that the mountain valley was a good place to settle. While there were members of The Church of Jesus Christ of Latter-day Saints who settled there, a bustling town soon sprang up with shops, saloons, hotels, a Masonic Hall, and churches of various denominations. A teacher's college was established in 1894.

In the early 1900's, the Minidoka Project, a reclamation program, built dams on the Snake River, establishing a series of canals which opened thousands of acres of fertile land in the Magic Valley for irrigation. The influx of people coming to claim the land established the towns of Burley, Rupert, Twin Falls, Declo, etc. Many people found farming the fertile soil with plentiful water a much more profitable lifestyle than the small ranches scattered along the creeks of the west. "In 1904, the lower Minidoka Project area around the present cities of Burley and Rupert was a nearly uninhabited sagebrush desert with only a few scattered ranches. After construction of the initial phases of the project brought water to the land, giving opportunity for expansion, it became a prosperous, highly developed farm area. By 1919, 2,208 farms were in operation, there were 6 towns, and the total population was about 17,000."

Probate Records
As of April, 2010, the earliest probate case files are found in the Cassia County Recorder's Office vault on the main floor of the courthouse located in Burley, Idaho. They have been removed from the old tri-fold metal boxes and put into six bankers boxes. No efforts have been made to unfold them but the packets have been put into alphabetical order. At that time, the staff were unable to find the probate proceedings or minute book series. One or two of the earliest dockets/registers are located in the main Clerk's vault but it appears that the series as a whole is not where one would expect. Researchers may locate files and registers for this county at the Idaho State Archives as records are being transferred on a regular basis.
