The oldest surviving building in West Haven is the Ward-Heitmann House at 277 Elm Street. It may have been built as early as 1684 and was certainly on the site by 1725. The house was built by Ebenezer Clark, who sold it in 1730 to John Humphreville, who had married Clark’s sister Rebecca. The house remained in the Clark family until 1788, when it was purchased by sea captain Thomas Ward (d. 1839). It remained in the Ward family until George Ward sold it to Susan Perrin in 1861. She eventually sold it to Louisa Ward Heitmann, George Ward’s sister, in 1868. Her daughter, Henrietta Heitmann, inherited the house in 1897. She was engaged in various business ventures and also added the north wing to the house and used it as a dame school. The house passed out of the Ward-Heitmann family when Charles Elliott Pickett purchased it in 1910. In the twentieth century the house had a number of owners and for a time housed an antiques store and later a tearoom. The Milano family owned the house from 1949 to the early 1990s and left it to the National Trust for Historic Preservation, which sold it to the Ward-Heitmann House Museum Foundation in 1995. The house was then restored to become a museum.
