The area near National Avenue and Racine Avenue was the center of the old Yankee Settlement named Prospect Hill by Yankee Dr. John Ingersoll. Prospect Hill was a close-knit hamlet at the turn of the 19th century. Its 200 residents patronized or operated their mills, blacksmith and cooper shops, tree nursery and greenhouse. Included among them were a doctor, minister, surveyor, carpenter, well-digger, dressmaker, mason and teacher. Progress spelled D-O-O-M for this country’s hamlets. After WWI, the Model T took folks away from home. Rural free delivery closed local post offices and the little stores died. But let us not forget their stories. Prospect Hill was designated a local Historic District on November 19, 1991 by the New Berlin Landmarks Commission.
