Idaho County records differ vastly from county to county in both quality and quantity. Some have already been very carefully maintained while some have been substantially misused and mistreated. A certain amount of Idaho records have simply disappeared. For genealogists carrying out research in Idaho there’s no valuable replace to have an on-site search of county courthouse records. For Definitions of all court terms see the Genealogy Encyclopedia.
The county seat holds many county historical resources. The county recorder’s office has land records on file. Probate records can be accessed through the probate clerk. The district court clerk, meanwhile, holds court records. Some counties have vital records on file from before the time when it was mandatory to record such records. Court records, including minutes and judgments, from before the counties were formed are also available, along with some land records. The district court clerk’s office holds naturalization records, which generally start at the time when the county was founded.

List of Idaho Extinct Counties
Idaho seems to have counties that no longer are in existence. They were recognized by the state, provincial, or territorial authorities. Many of these counties were created and disbanded within the Nineteenth century; county boundaries have evolved very little since Nineteen hundred in the great most of states. These counties need to be researched when performing genealogy and family history research. Pay attention where the courthouse records went to if the county was eliminated or merged with some other county.
- Alturas County(1864-1895) – was a county in Idaho Territory and later the state of Idaho from 1864 to 1895. It covered an area larger than the states of Maryland, New Jersey, and Delaware combined. Most present-day southern Idaho counties were created at least in part from the original Alturas County area. The name Alturas comes from a Spanish word for “mountain summits” or “mountainous heights.” Alturas County was created by the Idaho Territorial Legislature in February 1864. Later that year the mining camp of Rocky Bar was designated the county seat. The county seat was moved to Hailey in 1882. In 1889, the Idaho Territorial Legislature created Elmore County and Logan County from parts of Alturas County. On March 5, 1895, to circumvent a recent state supreme court decision striking down an earlier county reorganization, the Idaho Legislature combined Alturas and Logan Counties into a new county called Blaine. Two weeks later on March 18, the southern portion of the newly-created Blaine County was split off to form Lincoln County with its county seat at Shoshone. Hailey remained the county seat of what was now Blaine County and Alturas County disappeared from the Idaho map.
- Lah-Toh County (1864-1867) – was a county in Idaho Territory from 1864 to 1867. Lah-Toh County was created by the Idaho Territorial Legislature in 1864 with Coeur d’Alene as its county seat. The name is Nez Perce for “the place of pine trees and sestle”. The county was abolished in 1867, although sources disagree whether the area was absorbed by Nez Perce County or Kootenai County. It is most likely Kootenai since Coeur d’Alene serves as that county’s county seat. The county was re-established in 1888 with different boundaries as Latah County.
- Logan County (1889-1895) – was a county in Idaho Territory and later the state of Idaho from 1889 to 1895. Logan County was created from parts of Alturas County by the Idaho Territorial Legislature in 1889 with Bellevue as its county seat. Six years later, the Idaho Legislature attempted to return Bellevue to Alturas County, but the plan was struck down by the state supreme court. In response on March 5, 1895, the Idaho Legislature combined Logan and Alturas Counties into a new county called Blaine. Two weeks later on March 18, the southern portion of the newly-created Blaine County was split off to form Lincoln County with its county seat at Shoshone and Logan County ceased to exist. Bellevue became part of Blaine County.
List of Idaho Counties with Burned Courthouses
The destruction to Idaho courthouses considerably has a effect on genealogists in just about every way. Not only are these historic buildings ripped from our lifetimes, so are the files they kept: marriage, wills, probate, land records, as well as others. Once destroyed they are gone permanently. Despite the fact that they have already been placed on mircofilm, computers and film burn as well. The most tragic aspect of this is the reason why nearly all of our courthouses are destroyed as a result of arsonist. Although, don’t assume all records were damaged or lost. Many Idaho counties have dealt with a loss of records due to courthouse fires, floods, and theft.
