The earliest part of the house at 613 Main Street in Portland was constructed in 1703 for Jonathan Warner. It was one room over one room with an end chimney (a style typical of Rhode Island). The house was enlarged over the years. Behind the northwest part was a section built in 1764 by sea captain Ithamar Pelton (1744-1806). The south part of the house was added in 1912 by William Gildersleeve.
