The Stone House in Deep River (which was known as Saybrook until 1947) was built in 1840 by Deacon Ezra Southworth for he and his new wife, Eunice Post Southworth. The house was built using stone quarried on the property. The original flat tin roof was later replaced by a gabled roof. A rear addition was constructed in 1881, just before the marriage of the Southworth’s son, Ezra Job Birney Southworth, to Fanny Shortland of Chester. The wraparound porch was added to the house in 1898. Deacon Ezra’s granddaughter, Ada Southworth Munson, who died in 1946, bequeathed the property to the Deep River Historical Society. It is now a house museum open to the public. On the property, there is also a late nineteenth century barn (now called the carriage house) and a section from an old bleach house, owned by Pratt, Read & Co., which was used for whitening ivory. At one time, Pratt Read in Deep River and Comstock, Cheney & Co. in Ivoryton, dominated the ivory products manufacturing industry in the U.S.
