We believe this house was built in the 1840s, as Greenmanville expanded. George Greenman & Co. rented its two apartments to employees of the company’s shipyard and textile mill. In the 1850s and 1860s it was occupied by the widow of a mill employee and the minister of the Greenmanville Seventh-Day Baptist Church. The dormer was added in the 1900s. Named for the family that last owned it, the Constantine House is used as an office building by Mystic Seaport Museum.
