History
Buffalo County was created on March 16, 1855 and organized on October 1, 1870. [6] [7] It was named after the once-prevalent bison herds of the Great Plains. [8]
The Union Pacific Railroad came to the area in 1866; [9] with additional settlers, the need to establish government was realized. Patrick Walsh, Martin Slattery, and a Sergeant Cody petitioned the governor to organize Buffalo County in 1869. [9] Wood River Centre (Shelton) was selected through election as county seat. Within a year, the seat was moved to Gibbon. [10] In 1874, voters selected Kearney as the seat. [11]
During the late 19th century and early 20th century, the Watson Ranch, existed in the county. The 8,000 acre ranch extended from the Platte River Valley on the south, to Nebraska's rolling hills on the north, to a point five miles west of downtown Kearney. [12] [13]
