The house at 61 Denison Avenue (formerly 14 Denison Avenue) in Mystic was built in 1853 for Ebenezer Morgan. This may be the Ebenezer Morgan (1831-1903) whose career is described in the Genealogical and Biographical Record of New London County, Connecticut (1905):

In early life he worked in the old Irons & Grinnell yard as a ship carpenter, later in the Greenman and Mallory yards, in the latter serving as a superintendent, but during the last forty years of his life he was employed in the Light House Department on the Atlantic coast, and for several years was superintendent of construction in the Third Light House District. By his uniform courtesy and characteristic integrity Mr. Morgan commanded the respect of all who knew him. He was well known in Masonic circles throughout the State, being a member of Charity and Relief Lodge of Mystic: Palestine Commandery, of New London; and Pyramid Temple, Mystic Shrine, of Bridgeport. He had taken the thirty-second degree. He was a trustee in the Methodist Church. Like other members of his family, he was a man gifted in many ways, and he developed talents in ship construction which brought him many important contracts. He designed and built the famous yacht “Dauntless,” the property of Mrs. Colt, of Hartford, and was also the builder of the steam yacht “Britanique,” a vessel 240 feet in length, owned in Baltimore. He was the superintendent of the great work of dredging in the Potomac river and filling in land around the Washington Monument, and under his superintendence the Erie Basin Dry Dock was constructed.
