Nebraska Historical Marker proclaiming O'Neill the Irish Capital of Nebraska — established by the Irish colonists who settled the Elkhorn Valley in 1874.

One of the most colorful leaders in the early development of Nebraska was General John O’Neill, founder of O’Neill. After leading several ill-fated raids against British military posts in Canada, 1866-1871, O’Neill lost his leading position in the Fenians--an American organization promoting Irish independence. Born in Ireland in 1834, he was a U. S. Army Officer from 1857 to 1864, when he became active in the Fenians. In 1871, though in disfavor with the leading Irish-American society, O’Neill did not give up the cause.
