According to Portrait of a River Town: The History and Architecture of Haddam, Connecticut (1984), by Janice P. Cunningham and Elizabeth Ann Warner, the house at 366 Saybrook Road in the Higganum section of Haddam was erected by Heman Brainerd (1754-1803) on land deeded to him in 1784 by his father, Phineas Brainerd (1720-1803), one of the original settlers of Higganum. It was described as a “new Dwelling House” in a 1794 deed, although town acessor’s records date the house to 1729. After the death of Heman’s widow, the house was purchased by James Gladwin and remained in his family for the rest of the nineteenth century. Dr. William H. Tremaine (1815-1883), a noted physician, lived in the house from 1850 to 1857, before he moved to Hartford. The house’s original stairway and chimney, destroyed by fire in the nineteenth century, were rebuilt by its later twentieth century owners.
