Rugby was founded in 1886 at a junction on the Great Northern Railway, where a branch line to Bottineau met the main line. The railroad promoters initially platted the town as Rugby Junction, getting the name Rugby from the town of Rugby in Warwickshire, England.[6] It was one of several sites along the Great Northern's transcontinental route between Devils Lake and Minot that were named after places in England (the others were Berwick, Leeds, Knox, Norwich, Penn, Surrey, Churches Ferry, Tunbridge, and York). When the community became a city, the Junction was dropped from the name.

Larimore had its start in the year 1881 by the building of the railroad through that territory. It is named for N. G. Larimore, who owned a large farm in the area

Bonita, Montana
Missoula County. Along the Clark Fork River east of Clinton, Bonita was once on the Milwaukee Road and Northern Pacific lines. Two railroad tunnels pass through the Beavertail Hill just east of the former Bonita townsite. The name apparently came from Mexican section hands working on the Northern Pacific tracks in the 1880's; “bonita” is Spanish for “beautiful”. A post office operated in Bonita from 1886 (June 19) to 1942 (August 2). John Lovell served as the first postmaster.

Bearmouth was a trading post for the placer mining camps of Beartown, Garnet and Coloma, located in the hills north of Bearmouth in Granite County, Montana, United States.
