 To the west, the Lispenard mill, built shortly after the house, stood at the end of what is now called Titus Mill Pond and still separates the neck from mainland.Half of this original pond was filled in, for the creation of athletic fields and a causeway across the Mill Pond in the early 1950s.The small promontory on which the house is sited may have been created with earthen fill in the nineteenth century.
