Washington Co.-The towns of DeSota and Cumings City no longer exist in Washington Co., NE. DeSota was incorporated into the town of Blair. Cumings City, a mile or two north of the town of Blair, was laid out in lots, but to my knowledge, only a few houses were built, and most of the land is now farm land. The cemetery still remains.
