The Federal-style house at 37 Park Street in Guilford was constructed in 1805 by builder Abraham Coan for Heli Hoadley and his wife, Mabel Ann Seward. Hoadley soon moved to New Haven. As described in The Hoadley Genealogy (1894) by Francis Bacon Trowbridge:
Heli Hoadley resided in New Haven, Conn., and carried on the business of making trucks, carts, wheelbarrows, etc. His shop was situated on State street on the homestead lot, where Osborne street has since been cut through. After his wife’s death he gave up his flourishing business, and the property was sold and divided between the children. He died at his son John’s in North Haven and was buried in the Grove Street cemetery in New Haven.
The house was then owned by the Reverend Aaron Dutton, who was minister at the First Congregational Church of Guilford from 1806 to 1842. He resigned because of dissension in the church concerning his abolitionist views, which his congregation deemed too radical. The house was also once home to Charles Hubbard, a writer, teacher and artist. Hubbard referred to his third floor studio as Hobgoblin Hall.
