Please add profiles of those who were born, lived or died in O'Brien County, Iowa.
The county was created in 1851 and named for William Smith O'Brien, 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.
