In 1955, what then remained of William Smith's original manor was primarily located in Ridge and was surrounded by the world growing up around it, in the form of the Brookhaven National Laboratory and the surrounding areas becoming increasingly populated.
In 1738, northern Ridge was settled by widower Samuel Randall of North Stonington, Connecticut; his only son Stephen Randall and his descendants farmed a plot of ground that Samuel had always referred to as "the Ridge" based on the geographical terrain.
