They first lived in the old log house on the home farm and then built the house at the Hamlin corners, now owned by John Howard. In 1856 they moved to the village into a house built by Warren Cooley, now owned by Vern Stiles. Mr. Barnum opened a store in the building which stood in the bank south of the Cobb store, which was built by David Stevenson. He afterward became the owner of the Cobb store and carried on business with Dr. Disbro. He afterward carried on the business alone until he retired from active business a few years ago. His children are Emma, Mary and Herbert. A son, Joseph, died some years ago.
