Bonner County, Idaho: A Genealogical Overview

Located in the northern tip of the Idaho Panhandle, Bonner County is a region of immense natural beauty, dominated by Lake Pend Oreille, the state’s largest lake, and the surrounding Selkirk and Cabinet Mountains. Its history is deeply tied to the timber industry, mining rushes, and the expansion of railroads into the American West. The county seat, Sandpoint, sits on the shores of the lake and serves as the economic and cultural hub for the area.

I. County Formation and Evolution

Understanding Bonner County’s formation from a larger parent county and its subsequent division is critical for locating the correct records for ancestors who settled in the Idaho Panhandle.

  • 1907: County Formed: Bonner County was established on February 21, 1907, by an act of the Idaho Legislature.
  • Parent County: It was created from the northern portion of Kootenai County. Records prior to 1907 for ancestors in this area would be located in Kootenai County records, with the county seat at Rathdrum.
  • Subsequent County Formations: Bonner County was partitioned itself just eight years after its creation. In 1915, its northern portion was used to form Boundary County. Researchers with ancestors in the Bonners Ferry area must be aware of this boundary change.
  • Name Origin: The county is named for Edwin L. Bonner, a merchant, ferry operator, and mail carrier who established a key ferry on the Kootenai River in 1864, facilitating travel and commerce in the region.
  • County Seat History: The county seat has been Sandpoint since the county’s formation in 1907.

II. Settlement and Early History

  • Early Inhabitants: The region was originally the homeland of the Kalispel and Kootenai peoples, who utilized the vast resources of Lake Pend Oreille and the surrounding forests for fishing, hunting, and gathering.
  • Pioneer Settlement and Economy: The first significant non-native settlement was driven by the discovery of gold in the broader region and, most importantly, the arrival of the Northern Pacific Railroad in 1882. The railroad established Sandpoint as a crucial division point. The economy was built on the timber industry, with immense forests fueling sawmills and providing employment for thousands. Mining, particularly for silver and lead in the mountains, also drew prospectors and settlers. Agriculture and tourism developed alongside these primary industries.
