Atypical for Connecticut, the house at 75 Rope Ferry Road in Waterford (pdf) was constructed of granite ashlar blocks. The stone was quarried in Waterford. Known as the Stone House and the Powers-Allyn-Rosenthal House, it was built in 1877 (date on the cornerstone), although the wing may be earlier. A later resident of the house was Beatrice Holt Rosenthal (1900-1981). Active in support of women’s rights, Rosenthal was a delegate to Democratic National Convention from Connecticut in 1956 and 1960 and a Democratic National Committeewoman in 1963.
