John McConihe (1834-1864) was born in Troy, Rensselaer County, New York. After graduating from Union College in 1853, he went on to study law at the University of Albany, earning his law degree in 1855. He began a successful law practice in Troy the same year. In 1857, he moved to Omaha, Nebraska, where he continued practicing law. When the Civil War broke out, he helped raise the 1st Nebraska Regiment and would be involved in several battles. He was killed in action during the battle of Cold Harbor in 1864, and was buried in Oakwood Cemetery in Troy. This collection includes correspondence, clippings, photographs, and memoirs. Although the collection ranges from 1857-1870, the majority of materials date from the early 1860s, when McConihe served during the War.
