History

By the time Iowa attained statehood (December 28, 1848), its Territorial Legislature had created 44 counties. On January 15, 1851, the new State Legislature created another 49 counties, defining them by lines of survey. O'Brien was among the 49 units thus created.''Columbia-Lippincott Gazetteer,'' (New York:Columbia University Press, 1952), p. 1363 It consists of four survey townships, each formed by 36 square miles arranged in a 6x6 layout, for a nominal 576 square miles total area. The county was named for

, a leader for Irish independence in 1848. The new county's first settler arrived in 1856; Hannibal H. Waterman brought his wife and a daughter to the southeast portion (present Waterman Township). His homestead formed the nucleus of the county's first community, and a small building was erected there to function as a courthouse. By 1872, the county comprised several small communities, and residents of those groups felt the county's business should be conducted in a more central location. An election was held, the outcome of which was to create a new county seat at its midpoint. A tract at the center of the county was surveyed and platted; its name ( Primghar) was created from the initials of eight persons involved with the platting. The previous courthouse building was transported to this new location. In 1874, a 35-foot square building was erected on the present location at a cost of $2,000, to replace the first structure. It was replaced in 1887 by a larger structure. The County Board of Supervisors authorized its construction, at a cost not to exceed $5,000 (the maximum amount the county was authorized to commit). To keep within this limit, members of the new community agreed to haul the building materials without charge from railroad stops at Sanborn and Paullina. The present
