The collection from the Nebraska Historial Society is actually two collections in one; Solomon D. Butcher photographs and the letters of the Uriah W. Oblinger family.
The photographs were taken from about 3,000 glass plate negatives crafted by Butcher. They actually captured as images the process of settlement in Nebraska between 1886 and 1912. Butcher photographed mainly in the central part of Nebraska in the counties of Custer, Buffalo, Dawson and Cherry. The Oblinger family letters cover such things as land, work, neighbors, crops, religious meetings, problems with grasshoppers, financial problems, and the Easter Blizzard of 1873. Uriah Oblinger came from Indiana to Fillmore County, Nebraska in 1873. Even if you have no family connection, you'll find these fascinating reading.
